53278292 | 10.1007/S11340-012-9669-2 | Hole cold expansion is a technique widely\ud
used to improve the fatigue life of components with\ud
holes, e.g. bolted or riveted joints. As it has been demonstrated\ud
in literature by analytical, numerical and experimental\ud
analyses carried out by several authors, the\ud
compressive residual stresses introduced by the hole cold\ud
expansion have a beneficial influence on both the static\ud
and the fatigue strength of the treated component, because\ud
they reduce significantly the typical stress peaks\ud
around the hole due to stress concentration. In the literature,\ud
various analyses of the residual stresses introduced\ud
by the hole cold expansion have been performed by\ud
using several methods such as X-ray diffraction, neutron\ud
diffraction and the modified Sachs method. Unfortunately,\ud
all these method are affected by some limitations: low\ud
measurement depth (X-ray method), complex measurement\ud
procedure (neutron diffraction method) and approximate\ud
formulation (Sachs method). In order to overcome\ud
such drawbacks, in this study a new mechanical method,\ud
based on an innovative extension of the “rectilinear\ud
groove method” associated with the classical “integral\ud
method” calculation procedure, is proposed. Experimental\ud
assessment of the proposed method has been performed\ud

25052680 | 10.1007/S11425-015-5105-2 | Classical Kolmogorov's and Rosenthal's inequalities for the maximum partial
sums of random variables are basic tools for studying the strong laws of large
numbers. In this paper, motived by the notion of independent and identically
distributed random variables under the sub-linear expectation initiated by Peng
(2006, 2008b), we introduce the concept of negative dependence of random
variables and establish Kolmogorov's and Rosenthal's inequalities for the
maximum partial sums of negatively dependent random variables under the
sub-linear expectations. As an application, we show that Kolmogorov's strong
law of larger numbers holds for independent and identically distributed under a
continuous sub-linear expectation if and only if the corresponding Choquet
integral is finite.Comment: 20 page | Rosenthal's inequalities for independent and negatively dependent random

2127000 | 10.1007/S11538-010-9582-8 | Agent-based modeling and simulation is a useful method to study biological
phenomena in a wide range of fields, from molecular biology to ecology. Since
there is currently no agreed-upon standard way to specify such models it is not
always easy to use published models. Also, since model descriptions are not
usually given in mathematical terms, it is difficult to bring mathematical
analysis tools to bear, so that models are typically studied through
simulation. In order to address this issue, Grimm et al. proposed a protocol
for model specification, the so-called ODD protocol, which provides a standard
way to describe models. This paper proposes an addition to the ODD protocol
which allows the description of an agent-based model as a dynamical system,
which provides access to computational and theoretical tools for its analysis.
The mathematical framework is that of algebraic models, that is, time-discrete
dynamical systems with algebraic structure. It is shown by way of several
examples how this mathematical specification can help with model analysis.Comment: To appear in Bulletin of Mathematical Biolog | A Mathematical Framework for Agent Based Models of Complex Biological

160181817 | 10.1007/S11661-008-9 | Rapid-solidification experiments were conducted for understanding dent defects formed during strip casting of twin-induced plasticity (TWIP) steels. The rapid-solidification experiments reproduced the dent defects formed on these steels, which were generally located at valleys of the shot-blasted roughness on the substrate. The rapid-solidification experiment results reveal that the number of dips, the Mn content of the steel, and the surface roughness of the substrate affect the depth and size of dents formed on the solidified-shell surfaces, while the composition of the atmosphere gases and the carbon content of the steel are not factors. The formation of dents was attributed to the entrapment of gases inside the roughness valleys of the substrate surface and their volume expansion due to the temperature of the steel melt and the latent heat. The dents could be prevented when the thermal expansion of gases was suppressed by making longitudinal grooves on the substrate surface, which allowed the entrapped gases to escape. Sound solidified shells were obtained by optimizing the width and depth of the longitudinal grooves and by controlling the shot-blasting conditions.ope | Analysis and prevention of dent defects formed during strip casting of twin-induced plasticity steels | analysis and prevention of dent defects formed during strip casting of twin-induced plasticity steels | solidification dent defects strip casting twin plasticity twip steels. solidification reproduced dent defects steels valleys shot blasted roughness substrate. solidification reveal dips steel roughness dents solidified atmosphere gases steel factors. dents attributed entrapment gases roughness valleys steel melt latent heat. dents prevented gases suppressed longitudinal grooves entrapped gases escape. sound solidified shells optimizing longitudinal grooves controlling shot blasting conditions.ope | non_dup | [] |

The hot-rolling test results indicated that the Cr oxide layer formed in a heating furnace was broken off and infiltrated the steel, thereby forming Cr oxides on the rolled steel surface. Because the surface region without oxides underwent a reduction in hardness rather than the surface region with oxides, the thickness of the surface oxide layer favorably affected the resistance to sticking. The addition of Zr, Cu, and Ni to the ferritic stainless steels worked in favor of the decreased sticking, but the Si addition negatively affected the resistance to sticking. In the Si-rich steel, Si oxides were continuously formed along the interfacial area between the Cr oxide layer and the base steel, and interrupted the formation and growth of the Cr oxide layer. Because the Si addition played a role in increasing sticking, the reduction in Si content was desirable for preventing sticking.In the present study, mechanisms of sticking that occurs during hot rolling of modified STS430J1L ferritic stainless steels were investigated by using a pilot-plant-scale rolling machine, and the effects of alloying elements on sticking were analyzed by the high-temperature oxidation behavior.

The effects of particle size on the sintering behavior are critical to not only shape retention of microstructure but also its mechanical properties. This study investigates the effects of three different particle sizes on the sintering behavior of the 316L stainless steel (STS316L) samples, prepared by powder injection molding, via the dilatometry experiments. For this purpose, the STS316L powders of three different mean particle sizes, i.e., 2.97, 4.16, and 8.04 mu m, were produced for STS316L.

In stress-strain curves of the high-Mn steels, serrations started in a fine and short shape, and their height and periodic interval increased with increasing strain, whereas the Al-added steel did not show any serrations. According to digital images of strain rate and strain obtained from a vision strain gage system, deformation bands were initially formed at the upper region of the gage section, and moved downward along the tensile loading direction. The time when the band formation started was matched with the time when one serration occurred in the stress-time curve. This serration behavior was generally explained by dynamic strain aging, which was closely related with the formation of deformation bands.

Effects of pore size and shape were investigated, and three different cases of pore closure results were observed: no closure, partial closure, and full closure. The FEM results well reproduced various closure events. Bonding strengths of unsuccessfully closed pores, measured by tensile tests, showed critical effects. Also, there was a difference in bonding strengths of several fully closed pores. Fracture surfaces showed that welded regions could be divided into three (not, partially, and perfectly) welded regions. The pressure-time curves obtained from the FEM results indicate that pore surface contact time and deformed surface length are important parameters in pore welding. Pore size, pore shape, time of pressure contact, and deformed surface length should be considered to completely eliminate pores in final products.ope | Finite element and experimental analyses of closure and contact bonding of pores during hot rolling of steel | finite element and experimental analyses of closure and contact bonding of pores during hot rolling of steel | closure bonding pores steel slabs rolling pore pore closure closure closure closure. reproduced closure events. bonding strengths unsuccessfully pores tensile effects. bonding strengths pores. fracture welded divided partially perfectly welded regions. pore deformed pore welding. pore pore deformed eliminate pores products.ope | non_dup | [] |

148817126 | 10.1007/S11661-016-3433-7 | The microstructural evolution with varying intercritical-annealing temperatures of medium-Mn (alpha + gamma) duplex lightweight steels and its effects on tensile properties were investigated in relation to the stability of austenite. The size and volume fraction of austenite grains increased as the annealing temperature increased from 1123 K to 1173 K (850 A degrees C to 900 A degrees C), which corresponded with the thermodynamic calculation data. When the annealing temperature increased further to 1223 K (950 A degrees C), the size and volume fraction were reduced by the formation of athermal alpha'-martensite during the cooling because the thermal stability of austenite deteriorated as a result of the decrease in C and Mn contents. In order to obtain the best combination of strength and ductility by a transformation-induced plasticity (TRIP) mechanism, an appropriate mechanical stability of austenite was needed and could be achieved when fine austenite grains (size: 1.4 mu m, volume fraction: 0.26) were homogenously distributed in the ferrite matrix, as in the 1123 K (850 A degrees C)-annealed steel. This best combination was attributed to the requirement of sufficient deformation for TRIP and the formation of many deformation bands at ferrite grains in both austenite and ferrite bands. Since this medium-Mn lightweight steel has excellent tensile properties as well as reduced alloying costs and weight savings, it holds promise for new automotive applications.

160182187 | 10.1007/S11663-014-0034-Y | Crystallization behaviors of the newly developed lime-alumina-based mold fluxes for high-aluminum transformation induced plasticity (TRIP) steels casting were experimentally studied, and compared with those of lime-silica-based mold fluxes. The effects of mold flux crystallization characteristics on heat transfer and lubrication performance in casting high-Al TRIP steels were also evaluated. The results show that the crystallization temperatures of lime-alumina-based mold fluxes are much lower than those of lime-silica-based mold fluxes. Increasing B2O3 addition suppresses the crystallization of lime-alumina-based mold fluxes, while Na2O exhibits an opposite effect. In continuous cooling of lime-alumina-based mold fluxes with high B2O3 contents and a CaO/Al2O3 ratio of 3.3, faceted cuspidine precipitates first, followed by needle-like CaO center dot B2O3 or 9CaO center dot 3B(2)O(3)center dot CaF2. In lime-alumina-based mold flux with low B2O3 content (5.4 mass pct) and a CaO/Al2O3 ratio of 1.2, the formation of fine CaF2 takes place first, followed by blocky interconnected CaO center dot 2Al(2)O(3) as the dominant crystalline phase, and rod-like 2CaO center dot B2O3 precipitates at lower temperature during continuous cooling of the mold flux. In B2O3-free mold flux, blocky interconnected 3CaO center dot Al2O3 precipitates after CaF2 and 3CaO center dot 2SiO(2) formation, and takes up almost the whole crystalline fraction. The casting trials show that the mold heat transfer rate significantly decreases near the meniscus during the continuous casting using lime-alumina-mold fluxes with higher crystallinity, which brings a great reduction of surface depressions on cast slabs. However, excessive crystallinity of mold flux causes poor lubrication between mold and solidifying steel shell, which induces various defects such as drag marks on cast slab. Among the studied mold fluxes, lime-alumina-based mold fluxes with higher B2O3 contents and a CaO/Al2O3 ratio of 3.3 show comparatively improved performance.ope | Crystallization Characteristics of CaO-Al2O3-Based Mold Flux and Their Effects on In-Mold Performance during High-Aluminum TRIP Steels Continuous Casting | crystallization characteristics of cao-al2o3-based mold flux and their effects on in-mold performance during high-aluminum trip steels continuous casting | crystallization behaviors newly lime alumina mold fluxes aluminum plasticity trip steels casting experimentally lime silica mold fluxes. mold crystallization lubrication casting trip steels evaluated. crystallization lime alumina mold fluxes lime silica mold fluxes. suppresses crystallization lime alumina mold fluxes exhibits opposite effect. cooling lime alumina mold fluxes contents faceted cuspidine precipitates needle lime alumina mold fine blocky interconnected crystalline precipitates cooling mold flux. mold blocky interconnected precipitates crystalline fraction. casting mold meniscus casting lime alumina mold fluxes crystallinity brings great depressions cast slabs. excessive crystallinity mold lubrication mold solidifying steel induces defects drag marks cast slab. mold fluxes lime alumina mold fluxes contents comparatively performance.ope | non_dup | [] |
148817140 | 10.1007/S11663-015-0358-2 | A kinetic study for isothermal melt crystallization of CaO-SiO2-CaF2-based mold fluxes with different basicity of 0.94 and 1.34 has been carried out systematically by DSC measurements. The kinetic parameters were determined by Johnson-Mehl-Avrami equation. The average Avrami exponent of cuspidine (3CaO center dot 2SiO(2)center dot CaF2) crystallization for mold flux of lower basicity (0.94) is calculated to be 3.1, implying that the crystallization mode is instantaneous nucleation followed by 3-dimensional growth. For the mold flux of higher basicity (1.34), the average Avrami exponent of cuspidine equals to 3.4, strongly suggesting that the growth is still 3 dimensional but the nucleation should be continuous. It was found that the effective crystallization rate constant for both mold fluxes increases as the crystallization temperature decreases, showing that the crystallization rate could be governed by nucleation rate. The negative effective activation energy indicates an anti-Arrhenius behavior for crystallization of the mold fluxes studied. Therefore, it is concluded that the melt crystallization for the commercial mold fluxes will be determined by thermodynamics of nucleation which is relevant to degree of undercooling. The morphology of cuspidine crystals observed by SEM agreeds well with the isothermal crystallization kinetics results.open16 | Kinetics of Isothermal Melt Crystallization in CaO-SiO2-CaF2-Based Mold Fluxes | kinetics of isothermal melt crystallization in cao-sio2-caf2-based mold fluxes | isothermal melt crystallization mold fluxes basicity systematically measurements. johnson mehl avrami equation. avrami exponent cuspidine crystallization mold basicity implying crystallization instantaneous nucleation growth. mold basicity avrami exponent cuspidine equals nucleation continuous. crystallization mold fluxes crystallization crystallization governed nucleation rate. arrhenius crystallization mold fluxes studied. concluded melt crystallization commercial mold fluxes thermodynamics nucleation undercooling. morphology cuspidine crystals agreeds isothermal crystallization kinetics results.open | non_dup | [] |
148817138 | 10.1007/S11663-015-0459-Y | Cu, as one of the typical tramp elements, is known to cause hot shortness during reheating of slabs followed by hot rolling of sheet products. In order to prevent such harmful aspects, a new idea is proposed by using synthetic powders containing NiO in the mold flux during continuous casting of the slab. During the casting, NiO is reduced and absorbed on initial solidified steel shell, and a Ni-rich layer is developed near the surface region of the slab. According to the proposed idea, it is expected that both the Cu solubility and the melting temperature of Cu-segregated region would increase considerably by virtue of Ni-rich layer, which is believed to play an important role to prevent the Cu hot shortness. A series of laboratory-scale experiments were carried out in order to confirm the reduction and the absorption of Ni into the steel matrix. It was observed by SEM-EDS and FE-EPMA that a Ni-enriched layer, as thick as a few hundred mu m, formed near the surface of the slab. Also, a number of laboratory-scale heat treatment tests under oxidizing atmosphere showed that the samples with the Ni-enriched layer had a decreased Cu enrichment at the interface between scale and steel, compared to a case without Ni-rich layer. A pilot-plant-scale steel slab (medium carbon steel containing 0.3 wt pct Cu) was obtained in a continuous casting process with the NiO-containing mold flux, and a Ni-enriched layer was also observed. It was concluded that the use of NiO in the mold flux is a promising new approach for suppressing the hot shortness of Cu-containing steel, without an expensive addition of Ni to the whole steel matrix.Cu, as one of the typical tramp elements, is known to cause hot shortness during reheating of slabs followed by hot rolling of sheet products. In order to prevent such harmful aspects, a new idea is proposed by using synthetic powders containing NiO in the mold flux during continuous casting of the slab. During the casting, NiO is reduced and absorbed on initial solidified steel shell, and a Ni-rich layer is developed near the surface region of the slab. According to the proposed idea, it is expected that both the Cu solubility and the melting temperature of Cu-segregated region would increase considerably by virtue of Ni-rich layer, which is believed to play an important role to prevent the Cu hot shortness. A series of laboratory-scale experiments were carried out in order to confirm the reduction and the absorption of Ni into the steel matrix.

148817139 | 10.1007/S11663-015-0528-2 | Melt crystallization behavior of both the fluorine-containing and fluorine-free mold fluxes has been investigated using a single hot thermocouple technique (SHTT). By increasing the dew point of atmosphere from 223 K to 285.5 K (-50 A degrees C and 12.5 A degrees C), the primary crystalline phase of fluorine-containing mold flux was changed from cuspidine (Ca4Si2O7F2) to Ca2SiO4 with accelerated nucleation rates. Enhancement of fluorine evaporation due to hydroxyl is attributed to the main reason for the abnormal crystallization behavior of the fluorine-containing mold flux under humid atmosphere, which may bring a sticking-type breakout during the commercial continuous casting process. In contrast, the effect of water vapor on crystallization of fluorine-free mold flux was negligible. This implies that the application of fluorine-free mold fluxes can become a countermeasure to prevent the hydrogen-induced breakout during the continuous casting process under wet atmosphere.open1 | Effect of Water Vapor on Evaporation and Melt Crystallization of Mold Fluxes | effect of water vapor on evaporation and melt crystallization of mold fluxes | melt crystallization fluorine fluorine mold fluxes thermocouple shtt atmosphere crystalline fluorine mold changed cuspidine accelerated nucleation rates. enhancement fluorine evaporation hydroxyl attributed abnormal crystallization fluorine mold humid atmosphere bring sticking breakout commercial casting process. vapor crystallization fluorine mold negligible. fluorine mold fluxes countermeasure prevent breakout casting atmosphere.open | non_dup | [] |
161803439 | 10.1007/S11704-015-4472-8 | In the last decade, functional-structural plant modelling (FSPM) has become a more widely accepted paradigm in crop and tree production, as 3D models for the most important crops have been proposed. Given the wider portfolio of available models, it is now appropriate to enter the next level in FSPM development, by introducing more efficient methods for model development. This includes the consideration of model reuse (by modularisation), combination and comparison, and the enhancement of existing models. To facilitate this process, standards for design and communication need to be defined and established. We present a first step towards an efficient and general, i.e., not speciesspecific FSPM, presently restricted to annual or bi-annual plants, but with the potential for extension and further generalization.
Model structure is hierarchical and object-oriented, with plant organs being the base-level objects and plant individual and canopy the higher-level objects. Modules for the majority of physiological processes are incorporated, more than in other platforms that have a similar aim (e.g., photosynthesis, organ formation and growth). Simulation runs with several general parameter sets adopted from the literature show that the present prototypewas able to reproduce a plausible output range for different crops (rapeseed, barley, etc.) in terms of both the dynamics and final values (at harvest time) of model state variables such as assimilate production, organ biomass, leaf area and architecture | FSPM-P: towards a general functional-structural plant model for robust and comprehensive model development | fspm-p: towards a general functional-structural plant model for robust and comprehensive model development | decade fspm widely paradigm crop crops proposed. wider portfolio enter fspm introducing development. consideration reuse modularisation enhancement models. facilitate standards established. i.e. speciesspecific fspm presently restricted generalization. hierarchical oriented organs canopy objects. modules majority physiological incorporated platforms e.g. photosynthesis organ runs adopted prototypewas reproduce plausible crops rapeseed barley etc. harvest assimilate organ biomass leaf architecture | non_dup | [] |

Pea protein hydrolysates were prepared using the combination of Alcalase and Flavourzyme. The influence of the process variables was studied to optimize the proteolytic degradation to high degrees of hydrolysis. The average peptide chain lengths were obtained at 3–5 amino acid units after a hydrolysis of 30 min with the mixture of enzymes. Then, N-acylation in water, in presence of acid chloride (C12 and C16), carried out with a conversion rate of amine functions of 90%, allowed to obtain anionic surfactant mixtures (lipopeptides and sodium fatty acids). These two steps were performed in water, in continuous and did not generate any waste. This process was therefore in line with green chemistry principles.

Aminolysis with a secondary amine promotes the condensation reaction and limits the formation of glycerol. The ratio of α versus β was determined by zgig 13C NMR. This technique permits computing the yield of α and β products in the medium. The quantity of glycerol was determined by GC analysis. The ratio of the isomers and the amount of glycerol depend on the amine and the solvent.

75988595 | 10.1007/S12094-009-0328-8 | [Abstract] In recent years, it has been proposed that tumours are not homogeneous but composed of several cellular types like normal tissues. A cellular subtype, which is though to be the origin of tumours as well as their malignant properties (i.e., capacity for regrowth and metastasis), are the cancer stem cells (CSCs). CSCs, like normal stem cells, have a nearly unlimited capacity to self-renew and to proliferate so that are responsible, besides their same auto-perpetuation giving rise to the features previously depicted, also for the generation of the bulk of more differentiated cells in tumour. The altered behaviour of CSCs may be caused by the malfunction of a number of signalling pathways involved in normal embryonic development and in tissue homeostasis in adulthood. Among these signalling pathways are Wnt, Hedgehog, Notch and BMP pathways. In this review, we will focus on the study of molecular aspects of BMP signalling as well as its involvement in cancer | Biology of BMP signalling and cancer | biology of bmp signalling and cancer | tumours homogeneous composed tissues. subtype tumours malignant i.e. regrowth metastasis cscs cscs nearly unlimited renew proliferate besides auto perpetuation giving depicted differentiated tumour. altered cscs malfunction signalling pathways embryonic homeostasis adulthood. signalling pathways hedgehog notch pathways. signalling involvement | non_dup | [] |

189430009 | 10.1007/S40722-017-0095-5 | In this paper, we model Rogue Waves as localized instabilities emerging from homogeneous and stationary background wavefields, under NLS dynamics. This is achieved in two steps: given any background Fourier spectrum P(k), we use the Wigner transform and Penrose’s method to recover spatially periodic unstable modes, which we call unstable Penrose modes. These can be seen as generalized Benjamin–Feir modes, and their parameters are obtained by resolving the Penrose condition, a system of nonlinear equations involving P(k). Moreover, we show how the superposition of unstable Penrose modes can result in the appearance of localized unstable modes. By interpreting the appearance of an unstable mode localized in an area not larger than a reference wavelength λ0 as the emergence of a Rogue Wave, a criterion for the emergence of Rogue Waves is formulated. Our methodology is applied to δ spectra, where the standard Benjamin–Feir instability is recovered, and to more general spectra. In that context, we present a scheme for the numerical resolution of the Penrose condition and estimate the sharpest possible localization of unstable modes.

28949260 | 10.1007/dcr.0b013e31819c9a2c | PURPOSE: This study was designed to test whether metabolic characterization of intact, unaltered human rectal adenocarcinoma specimens is possible using the high-resolution magic angle spinning proton (1H) magnetic resonance spectroscopy technique. METHODS: The study included 23 specimens from five patients referred for ultrasonographic staging of suspected rectal cancer. Multiple biopsies of macroscopically malignant rectal tumors and benign rectal mucosa were obtained from each patient for a total of 14 malignant and 9 benign samples. Unaltered tissue samples were spectroscopically analyzed. Metabolic profiles were established from the spectroscopy data and correlated with histopathologic findings. RESULTS: Metabolomic profiles represented by principle components of metabolites measured from spectra differentiated between malignant and benign samples and correlated with the volume percent of cancer (P = 0.0065 and P = 0.02, respectively) and benign epithelium (P = 0.0051 and P = 0.0255, respectively), and with volume percent of stroma, and inflammation. CONCLUSIONS: Magnetic resonance spectroscopy of rectal biopsies has the ability to metabolically characterize samples and differentiate between pathological features of interest.

10128264 | 10.1007/jhep01(2012)022 | We analyze the structure of matter representations arising from codimension two singularities in F-theory, focusing on gauge groups SU(N). We give a detailed local description of the geometry associated with several types of singularities and the associated matter representations. We also construct global F-theory models for 6D and 4D theories containing these matter representations. The codimension two singularities encountered include examples where the apparent Kodaira singularity type does not need to be completely resolved to produce a smooth Calabi-Yau, examples with rank enhancement by more than one, and examples where the 7-brane configuration is singular. We identify novel phase transitions, in some of which the gauge group remains fixed but the singularity type and associated matter content change along a continuous family of theories. Global analysis of 6D theories on ℙ[superscript 2] with 7-branes wrapped on curves of small degree reproduces the range of 6D supergravity theories identified through anomaly cancellation and other consistency conditions. Analogous 4D models are constructed through global F-theory compactifications on ℙ[superscript 3], and have a similar pattern of SU(N) matter content. This leads to a constraint on the matter content of a limited class of 4D supergravity theories containing SU(N) as a local factor of the gauge group.United States.

55632541 | 10.1007/jhep01(2013)116 | A search for resonances produced in 7 TeV proton-proton collisions and decaying into top-quark pairs is described. In this Letter events where the top-quark decay produces two massive jets with large transverse momenta recorded with the ATLAS detector at the Large Hadron Collider are considered. Two techniques that rely on jet substructure are used to separate top-quark jets from those arising from light quarks and gluons.

breaking scenarios is performed in pp collisions at √

78052983 | 10.1007/jhep01(2014)096 | A search for the standard model Higgs boson decaying to a W-boson pair at the LHC is reported. The event sample corresponds to an integrated luminosity of 4.9 fb[superscript −1] and 19.4 fb[superscript −1] collected with the CMS detector in pp collisions at √s = 7 and 8 TeV, respectively. The Higgs boson candidates are selected in events with two or three charged leptons. An excess of events above background is observed, consistent with the expectation from the standard model Higgs boson with a mass of around 125 GeV. The probability to observe an excess equal or larger than the one seen, under the background-only hypothesis, corresponds to a significance of 4.3 standard deviations for m [subscript H] = 125.6 GeV. The observed signal cross section times the branching fraction to WW for m [subscript H] = 125.6 GeV is 0.72[+0.20 over −0.18] times the standard model expectation. The spin-parity J [superscript P] = 0[superscript +] hypothesis is favored against a narrow resonance with J [superscript P] = 2[superscript +] or J [superscript P] = 0[superscript −] that decays to a W-boson pair.

In particular, we investigate its behavior near an IR fixed point using holographic duality. We develop techniques which, for any static holographic geometry, enable us to extract the large radius expansion of the entanglement entropy for a spherical region. We show that for both a sphere and a strip, the approach of the renormalized entanglement entropy to the IR fixed point value contains a contribution that depends on the whole RG trajectory. Such a contribution is dominant, when the leading irrelevant operator is sufficiently irrelevant. For a spherical region such terms can be anticipated from a geometric expansion, while for a strip whether these terms have geometric origins remains to be seen.United States.

A new circular e[superscript +]e[superscript −] collider hosted in a 80 to 100 km tunnel, TLEP, is among the most attractive solutions proposed so far. It has a clean experimental environment, produces high luminosity for top-quark, Higgs boson, W and Z studies, accommodates multiple detectors, and can reach energies up to the t[¯ over t] threshold and beyond. It will enable measurements of the Higgs boson properties and of Electroweak Symmetry-Breaking (EWSB) parameters with unequalled precision, offering exploration of physics beyond the Standard Model in the multi-TeV range. Moreover, being the natural precursor of the VHE-LHC, a 100 TeV hadron machine in the same tunnel, it builds up a long-term vision for particle physics. Altogether, the combination of TLEP and the VHE-LHC offers, for a great cost effectiveness, the best precision and the best search reach of all options presently on the market.

78061654 | 10.1007/jhep01(2015)086 | Many four-dimensional supersymmetric compactifications of F-theory contain gauge groups that cannot be spontaneously broken through geometric deformations. These “non-Higgsable clusters” include realizations of SU(3), SU(2), and SU(3) × SU(2), but no SU(n) gauge groups or factors with n > 3. We study possible realizations of the standard model in F-theory that utilize non-Higgsable clusters containing SU(3) factors and show that there are three distinct possibilities. In one, fields with the non-abelian gauge charges of the standard model matter fields are localized at a single locus where non-perturbative SU(3) and SU(2) seven-branes intersect; cancellation of gauge anomalies implies that the simplest four-dimensional chiral SU(3) × SU(2) × U(1) model that may arise in this context exhibits standard model families. We identify specific geometries that realize non-Higgsable SU(3) and SU(3) × SU(2) sectors.

78061655 | 10.1007/jhep01(2015)131 | We present the generalized Scherk-Schwarz reduction ansatz for the full supersymmetric exceptional field theory in terms of group valued twist matrices subject to consistency equations. With this ansatz the field equations precisely reduce to those of lower-dimensional gauged supergravity parametrized by an embedding tensor. We explicitly construct a family of twist matrices as solutions of the consistency equations. They induce gauged supergravities with gauge groups SO(p, q) and CSO(p, q, r). Geometrically, they describe compactifications on internal spaces given by spheres and (warped) hyperboloides H [superscript p,q], thus extending the applicability of generalized Scherk-Schwarz reductions beyond homogeneous spaces. Together with the dictionary that relates exceptional field theory to D = 11 and IIB supergravity, respectively, the construction defines an entire new family of consistent truncations of the original theories. These include not only compactifications on spheres of different dimensions (such as AdS[subscript 5] × S [superscript 5]), but also various hyperboloid compactifications giving rise to a higher-dimensional embedding of supergravities with non-compact and non-semisimple gauge groups.United States.

No evidence of a high-mass Higgs boson is found. Limits on σH × BR(H → WW) as a function of the Higgs boson mass mH are determined in three different scenarios: one in which the heavy Higgs boson has a narrow width compared to the experimental resolution, one for a width increasing with the boson mass and modeled by the complex-pole scheme following the same behavior as in the Standard Model, and one for intermediate widths. The upper range of the search is mH = 1500 GeV for the narrow-width scenario and mH = 1000 GeV for the other two scenarios. The lower edge of the search range is 200–300 GeV and depends on the analysis channel and search scenario. For each signal interpretation, individual and combined limits from the two WW decay channels are presented. At mH = 1500 GeV, the highest-mass point tested, σH × BR(H → WW) for a narrow-width Higgs boson is constrained to be less than 22 fb and 6.6 fb at 95% CL for the gluon fusion and vector-boson fusion production modes, respectively.We acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWFW and FWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; CONICYT, Chile; CAS, MOST and NSFC, China; COLCIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic; DNRF, DNSRC and Lundbeck Foundation, Denmark; EPLANET, ERC and NSRF, European Union; IN2P3-CNRS, CEA-DSM/IRFU, France; GNSF, Georgia; BMBF, DFG, HGF, MPG and AvH Foundation, Germany; GSRT and NSRF, Greece; RGC, Hong Kong SAR, China; ISF, MINERVA, GIF, I-CORE and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; FOM and NWO, Netherlands; BRF and RCN, Norway; MNiSW and NCN, Poland; GRICES and FCT, Portugal; MNE/IFA, Romania; MES of Russia and NRC KI, Russian Federation; JINR; MSTD, Serbia; MSSR, Slovakia; ARRS and MIZS, Slovenia; DST/NRF, South Africa; MINECO, Spain; SRC and Wallenberg Foundation, Sweden; SER, SNSF and Cantons of Bern and Geneva, Switzerland; NSC, Taiwan; TAEK, Turkey; STFC, the Royal Society and Leverhulme Trust, United Kingdom; DOE and NSF, United States of America | Search for a high-mass Higgs boson decaying to a W boson pair in pp collisions at root s=8TeV with the ATLAS detector | search for a high-mass higgs boson decaying to a w boson pair in pp collisions at root s=8tev with the atlas detector | boson ℓνℓν ℓνqq collision luminosity atlas hadron collider. boson found. boson scenarios boson narrow boson modeled pole widths. narrow scenarios. scenario. presented. narrow boson constrained gluon fusion boson fusion respectively.we acknowledge anpcyt argentina yerphi armenia australia bmwfw austria anas azerbaijan sstc belarus cnpq fapesp brazil nserc canada cern conicyt chile nsfc colciencias colombia msmt czech republic dnrf dnsrc lundbeck foundation denmark eplanet nsrf union cnrs irfu gnsf georgia bmbf foundation gsrt nsrf greece hong kong minerva benoziyo israel infn mext jsps cnrst morocco netherlands norway mnisw poland grices portugal romania russia russian federation jinr mstd serbia mssr slovakia arrs mizs slovenia africa mineco spain wallenberg foundation sweden snsf cantons bern geneva switzerland taiwan taek turkey stfc royal leverhulme trust kingdom america | non_dup | [] |

The dataset corresponds to an integrated luminosity of 20.3 fb−1, collected by the ATLAS detector in 2012 at the Large Hadron Collider at CERN. Events containing two leptons and one central b-jet are selected. The W t signal is separated from the backgrounds using boosted decision trees, each of which combines a number of discriminating variables into one classifier. Production of W t events is observed with a significance of 7.7σ. The cross-section is extracted in a profile likelihood fit to the classifier output distributions. The W t cross-section, inclusive of decay modes, is measured to be 23.0 ± 1.3(stat.)− 3.5+ 3.2(syst.)±1.1(lumi.) pb.

This measurement is based on 462.72 live days data, approximately twice as much data as in the previous such analysis, collected with a detector positioned at an average distance of 1050m from two reactor cores. Several novel techniques have been developed to achieve significant reductions of the backgrounds and systematic uncertainties. Accidental coincidences, the dominant background in this analysis, are suppressed by more than an order of magnitude with respect to our previous publication by a multi-variate analysis. These improvements demonstrate the capability of precise measurement of reactor (nu) over bar (e) without gadolinium loading. Spectral distortions from the (nu) over bar (e) reactor flux predictions previously reported with the neutron capture on gadolinium events are confirmed in the independent data sample presented here. A value of sin(2) 2 theta(13) = 0.095(0.039)(+0.039)(stat+syst) is obtained from a fit to the observed event rate as a function of the reactor power, a method insensitive to the energy spectrum shape. A simultaneous fit of the hydrogen capture events and of the gadolinium capture events yields a measurement of sin(2) 2 theta(13) = 0.088 +/- 0.033(stat+syst) | Measurement of theta(13) in Double Chooz using neutron captures on hydrogen with novel background rejection techniques | measurement of theta(13) in double chooz using neutron captures on hydrogen with novel background rejection techniques | citation appel abrahao almazan anjos chooz theta chooz neutron captures rejection techniques. jhep buck busenitz cabrera camilleri carr cerrada chauveau chimenti collin conrad crespo anadon crum cucoanes damon dawson dhooghe dietrich djurcic dracos etenko fallot feilitzsch felde fernandes fischer franco franke furuta botella giot goger neff gomez gonzalez goodenough goodman haag hara haser hellwig hofmann horton hourlier ishitsuka jochum jollet kaether kalousis kamyshkov kaneda kaplan kawasaki kemp kerret kryn kuze lachenmaier lane lasserre letourneau lhuillier lima lindner lopez castano losecco lubsandorzhiev lucht maeda mariani maricic martino matsubara mention meregaglia miletic milincic minotti nagasaka navas nicolas novella oberauer obolensky onillon osborn palomares pepe perasso porta pronost reichenbacher reinhold rohling roncin rybolt sakamoto santorelli schilithz schonert schoppmann shaevitz sharankova shrestha sibille sinev skorokhvatov soiron spitz stahl stancu stokes strait suekane sukhotin sumiyoshi svoboda terao tonazzo valdiviesso vassilopoulos veyssiere vivier wagner walsh watanabe wiebusch wurm yermia zimmer chooz collaborationthe chooz presents theta reactor beta neutron captured hydrogen. live twice positioned reactor cores. reductions backgrounds uncertainties. accidental coincidences suppressed publication variate analysis. improvements capability precise reactor gadolinium loading. distortions reactor neutron capture gadolinium confirmed here. theta stat syst reactor insensitive shape. simultaneous capture gadolinium capture theta stat syst | non_dup | [] |
76177474 | 10.1007/jhep01(2016)172 | A search for a Higgs boson produced via vector-boson fusion and decaying into invisible particles is presented, using 20.3 fb−1 of proton-proton collision data at a centre-of-mass energy of 8 TeV recorded by the ATLAS detector at the LHC. For a Higgs boson with a mass of 125 GeV, assuming the Standard Model production cross section, an upper bound of 0.28 is set on the branching fraction of H → invisible at 95% confidence level, where the expected upper limit is 0.31. The results are interpreted in models of Higgs-portal dark matter where the branching fraction limit is converted into upper bounds on the dark-matter-nucleon scattering cross section as a function of the dark-matter particle mass, and compared to results from the direct dark-matter detection experiments.We acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWF, Austria; AHAS, Azerbaijan; SSTC, Belarus; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; CONICYT, Chile; CAS, MOST and NSFC, China; COLCIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic; DNRF, DNSRC and Lundbeck Foundation, Denmark; ARTEMIS, European Union; IN2P3-CNRS, CEA-DSM/IRFU, France; GNAS, Georgia; BMBF, DFG, HGF, MPG and AvH Foundation, Germany; GSRT, Greece; ISF, MINERVA, GIF, DIP and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; FOM and NWO, Netherlands; RCN, Norway; MNiSW, Poland; GRICES and FCT, Portugal; MERYS (MECTS), Romania; MES of Russia and ROSATOM, Russian Federation; JINR; MSTD, Serbia; MSSR, Slovakia; ARRS and MVZT, Slovenia; DST/NRF, South Africa; MICINN, Spain; SRC and Wallenberg Foundation, Sweden; SER, SNSF and Cantons of Bern and Geneva, Switzerland; NSC, Taiwan; TAEK, Turkey; STFC, the Royal Society and Leverhulme Trust, United Kingdom; DOE and NSF, United States of America | Search for invisible decays of a Higgs boson using vector-boson fusion in pp collisions at root s=8 TeV with the ATLAS detector | search for invisible decays of a higgs boson using vector-boson fusion in pp collisions at root s=8 tev with the atlas detector | boson boson fusion decaying invisible proton proton collision atlas lhc. boson branching invisible confidence interpreted portal branching converted bounds nucleon experiments.we acknowledge anpcyt argentina yerphi armenia australia bmwf austria ahas azerbaijan sstc belarus cnpq fapesp brazil nserc canada cern conicyt chile nsfc colciencias colombia msmt czech republic dnrf dnsrc lundbeck foundation denmark artemis union cnrs irfu gnas georgia bmbf foundation gsrt greece minerva benoziyo israel infn mext jsps cnrst morocco netherlands norway mnisw poland grices portugal merys mects romania russia rosatom russian federation jinr mstd serbia mssr slovakia arrs mvzt slovenia africa micinn spain wallenberg foundation sweden snsf cantons bern geneva switzerland taiwan taek turkey stfc royal leverhulme trust kingdom america | non_dup | [] |
42629465 | 10.1007/jhep02(2010)054 | A complete analysis of all heterotic Calabi-Yau compactifications based on positive two-term monad bundles over favourable complete intersection Calabi-Yau threefolds is performed. We show that the original data set of about 7000 models contains 91 standard-like models which we describe in detail. A closer analysis of Wilson-line breaking for these models reveals that none of them gives rise to precisely the matter field content of the standard model. We conclude that the entire set of positive two-term monads on complete intersection Calabi-Yau manifolds is ruled out on phenomenological grounds. We also take a first step in analyzing the larger class of non-positive monads. In particular, we construct a supersymmetric heterotic standard model within this class. This model has the standard model gauge group and an additional U(1) B−L symmetry, precisely three families of quarks and leptons, one pair of Higgs doublets and no anti-families or exotics of any kind | Exploring positive monad bundles and a new heterotic standard model | exploring positive monad bundles and a new heterotic standard model | heterotic calabi compactifications monad bundles favourable intersection calabi threefolds performed. detail. closer wilson breaking reveals none precisely model. monads intersection calabi manifolds ruled phenomenological grounds. analyzing monads. supersymmetric heterotic class. precisely families quarks leptons doublets families exotics kind | non_dup | [] |
4426686 | 10.1007/jhep02(2010)099 | We develop a systematic framework for realizing general anomaly-free chiral 6D supergravity theories in F-theory. We focus on 6D (1, 0) models with one tensor multiplet whose gauge group is a product of simple factors (modulo a finite abelian group) with matter in arbitrary representations. Such theories can be decomposed into blocks associated with the simple factors in the gauge group; each block depends only on the group factor and the matter charged under it. All 6D chiral supergravity models can be constructed by gluing such blocks together in accordance with constraints from anomalies. Associating a geometric structure to each block gives a dictionary for translating a supergravity model into a set of topological data for an F-theory construction. We construct the dictionary of F-theory divisors explicitly for some simple gauge group factors and associated matter representations. Using these building blocks we analyze a variety of models. We identify some 6D supergravity models which do not map to integral F-theory divisors, possibly indicating quantum inconsistency of these 6D theories.United States.

9066671 | 10.1007/jhep02(2012)093 | N -subjettiness is a jet shape designed to identify boosted hadronic objects such as top quarks. Given N subjet axes within a jet, N-subjettiness sums the angular distances of jet constituents to their nearest subjet axis. Here, we generalize and improve on N -subjettiness by minimizing over all possible subjet directions, using a new variant of the k-means clustering algorithm. On boosted top benchmark samples from the BOOST2010 workshop, we demonstrate that a simple cut on the 3-subjettiness to 2-subjettiness ratio yields 20% (50%) tagging efficiency for a 0.23% (4.1%) fake rate, making N -subjettiness a highly effective boosted top tagger. N-subjettiness can be modified by adjusting an angular weighting exponent, and we find that the jet broadening measure is preferred for boosted top searches. We also explore multivariate techniques, and show that additional improvements are possible using a modified Fisher discriminant. Finally, we briefly mention how our minimization procedure can be extended to the entire event, allowing the event shape N-jettiness to act as a fixed N cone jet algorithm.Massachusetts Institute of Technology.

78053964 | 10.1007/jhep02(2013)075 | Finite gauge transformations in double field theory can be defined by the exponential of generalized Lie derivatives. We interpret these transformations as ‘generalized coordinate transformations’ in the doubled space by proposing and testing a formula that writes large transformations in terms of derivatives of the coordinate maps. Successive generalized coordinate transformations give a generalized coordinate transformation that differs from the direct composition of the original two. Instead, it is constructed using the Courant bracket. These transformations form a group when acting on fields but, intriguingly, do not associate when acting on coordinates.United States.

20024974 | 10.1007/jhep02(2013)097 | Both the robust INTEGRAL 511 keV gamma-ray line and the recent tentative hint of the 135 GeV gamma-ray line from Fermi-LAT have similar signal morphologies, and may be produced from the same dark matter annihilation. Motivated by this observation, we construct a dark matter model to explain both signals and to accommodate the two required annihilation cross sections that are different by more than six orders of magnitude. In our model, to generate the low-energy positrons for INTEGRAL, dark matter particles annihilate into a complex scalar that couples to photon via a charge-radius operator. The complex scalar contains an excited state decaying into the ground state plus an off-shell photon to generate a pair of positron and electron. Two charged particles with non-degenerate masses are necessary for generating this charge-radius operator. One charged particle is predicted to be long-lived and have a mass around 3.8 TeV to explain the dark matter thermal relic abundance from its late decay. The other charged particle is predicted to have a mass below 1 TeV given the ratio of the two signal cross sections. The 14 TeV LHC will concretely test the main parameter space of this lighter charged particle.University of Wisconsin--Madison (Start-up funds)SLAC National Accelerator Laboratory (US DOE contract DE-AC02-76SF00515)Aspen Center for Physics (NSF Grant No. 1066293)United States.

The angular distribution is measured in bins of dimuon invariant mass squared and found to be consistent with Standard Model expectations. Integrating the differential branching fraction over the full dimuon invariant mass range yields a total branching fraction of BB (B+ → K+μ+μ−) = (4.36 ± 0.15 ± 0.18) × 10−7.

78061653 | 10.1007/jhep02(2015)106 | We present a new framework for computing resummed and matched distributions in processes with many hard QCD jets. The intricate color structure of soft gluon emission at large angles renders resummed calculations highly non-trivial in this case. We automate all ingredients necessary for the color evolution of the soft function at next-to-leading-logarithmic accuracy, namely the selection of the color bases and the projections of color operators and Born amplitudes onto those bases. Explicit results for all QCD processes with up to 2 → 5 partons are given. We also devise a new tree-level matching scheme for resummed calculations which exploits a quasi-local subtraction based on the Catani-Seymour dipole formalism. We implement both resummation and matching in the Sherpa event generator. As a proof of concept, we compute the resummed and matched transverse-thrust distribution for hadronic collisions.United States. Dept. of Energy (Contract DE-AC02-76SF00515)United States.

42629440 | 10.1007/jhep02(2015)158 | Kreuzer and Skarke famously produced the largest known database of Calabi-Yau threefolds by providing a complete construction of all 473,800,776 reflexive polyhedra that exist in four dimensions [1]. These polyhedra describe the singular limits of ambient toric varieties in which Calabi-Yau threefolds can exist as hypersurfaces. In this paper, we review how to extract topological and geometric information about Calabi-Yau threefolds using the toric construction, and we provide, in a companion online database (see http://nuweb1.neu.edu/cydatabase), a detailed inventory of these quantities which are of interest to physicists. Many of the singular ambient spaces described by the Kreuzer-Skarke list can be smoothed out into multiple distinct toric ambient spaces describing different Calabi-Yau threefolds. We provide a list of the different Calabi-Yau threefolds which can be obtained from each polytope, up to current computational limits. We then give the details of a variety of quantities associated to each of these Calabi-Yau such as Chern classes, intersection numbers, and the Kähler and Mori cones, in addition to the Hodge data.

157767677 | 10.1007/jhep02(2016)105 | We study the strong coupling behaviour of 1/4-BPS circular Wilson loops (a family of “latitudes”) in N=4 Super Yang-Mills theory, computing the one-loop corrections to the relevant classical string solutions in AdS5 ×S5. Supersymmetric localization provides an exact result that, in the large ’t Hooft coupling limit, should be reproduced by the sigma-model approach. To avoid ambiguities due to the absolute normalization of the string partition function, we compare the ratio between the generic latitude and the maximal 1/2-BPS circle: any measure-related ambiguity should simply cancel in this way. We use the Gel’fand-Yaglom method with Dirichlet boundary conditions to calculate the relevant functional determinants, that present some complications with respect to the standard circular case. After a careful numerical evaluation of our final expression we still find disagreement with the localization answer: the difference is encoded into a precise “remainder function”.

The search is based on 20.3 fb−1 of proton-proton collision data taken at the LHC at a centre-of-mass energy of 8 TeV recorded by the ATLAS detector. Events with one or two leptons, and one, two or three jets are selected with the additional requirement that at least one jet contains a b-quark. Single-lepton events are also required to contain at least one large-radius jet from the hadronic decay of a high-pTW boson or a top quark. No significant excess over the expected background is observed and upper limits on the cross-section times branching ratio for different vector-like quark and excited-quark model masses are derived.

143976879 | 10.1007/jhep02(2017)117 | Ratios of top-quark pair to Z-boson cross sections measured from proton-proton collisions at the LHC centre-of-mass energies of √s=13 TeV, 8 TeV, and 7 TeV are presented by the ATLAS Collaboration. Single ratios, at a given √s for the two processes and at different √s for each process, as well as double ratios of the two processes at different √s, are evaluated. The ratios are constructed using previously published ATLAS measurements of the t¯t and Z-boson production cross sections, corrected to a common phase space where required, and a new analysis of Z → ℓ+ℓ− where ℓ = e, μ at √s=13 TeV performed with data collected in 2015 with an integrated luminosity of 3.2 fb−1. Correlations of systematic uncertainties are taken into account when evaluating the uncertainties in the ratios. The correlation model is also used to evaluate the combined cross section of the Z → e+e− and the Z → μ+μ− channels for each √s value. The results are compared to calculations performed at next-to-next-to-leading-order accuracy using recent sets of parton distribution functions.

4426271 | 10.1007/jhep03(2010)018 | We solve second order relativistic hydrodynamics equations for a boost-invariant 1+1-dimensional expanding fluid with an equation of state taken from lattice calculations of the thermodynamics of strongly coupled quark-gluon plasma. We investigate the dependence of the energy density as a function of proper time on the values of the shear viscosity η, the bulk viscosity ζ, and second order coefficients, confirming that large changes in the values of the latter have negligible effects. Varying the shear viscosity between zero and a few times s/4π, with s the entropy density, has significant effects, as expected based on other studies. Introducing a nonzero bulk viscosity also has significant effects. In fact, if the bulk viscosity peaks near the crossover temperature T c to the degree indicated by recent lattice calculations in QCD without quarks, it can make the fluid cavitate — falling apart into droplets. It is interesting to see a hydrodynamic calculation predicting its own breakdown, via cavitation, at the temperatures where hadronization is thought to occur in ultrarelativistic heavy ion collisions.United States.

2724547 | 10.1007/jhep03(2011)018 | In order to investigate the phenomenological implications of warped spaces in more than five dimensions, we consider a 4 + 1 + δ dimensional extension to the Randall and Sundrum model in which the space is warped with respect to a single direction by the presence of an anisotropic bulk cosmological constant. The Einstein equations are solved, giving rise to a range of possible spaces in which the δ additional spaces are warped. Here we consider models in which the gauge fields are free to propagate into such spaces. After carrying out the Kaluza Klein (KK) decomposition of such fields it is found that the KK mass spectrum changes significantly depending on how the δ additional dimensions are warped. We proceed to compute the lower bound on the KK mass scale from electroweak observables for models with a bulk SU(2) × U(1) gauge symmetry and models with a bulk SU(2) R × SU(2) L × U(1) gauge symmetry. It is found that in both cases the most favourable bounds are approximately M KK ≳ 2 TeV, corresponding to a mass of the first gauge boson excitation of about 4 – 6 TeV.

We discuss gauge fixing of the free theory in a simple class of gauges using the Faddeev-Popov method. We find that the world-sheet ghost number of ghost and antighost string fields ranges over all integers, except one, and at any fixed ghost number, only a finite number of picture numbers appear. We calculate the propagators in a variety of gauges and determine the field-antifield content and the free master action in the Batalin-Vilkovisky formalism.

17029436 | 10.1007/jhep03(2012)049 | Recent LHC bounds on squark masses combined with naturalness and flavor considerations motivate non-trivial sfermion mass spectra in the supersymmetric Standard Model. These can arise if supersymmetry breaking is communicated to the visible sector via new extended gauge symmetries. Such extended symmetries must be spontaneously broken, or confined, complicating the calculation of soft masses. We develop a new formalism for calculating perturbative gauge-mediated two-loop soft masses for gauge groups with arbitrary patterns of spontaneous symmetry breaking, simplifying the framework of “Higgsed gauge mediation.” The resulting expressions can be applied to Abelian and non-Abelian gauge groups, opening new avenues for supersymmetric model building. We present a number of examples using our method, ranging from grand unified threshold corrections in standard gauge mediation to soft masses in gauge extensions of the Higgs sector that can raise the Higgs mass through non-decoupling D-terms. We also outline a new mediation mechanism called “flavor mediation”, where supersymmetry breaking is communicated via a gauged subgroup of Standard Model flavor symmetries. Flavor mediation can automatically generate suppressed masses for third-generation squarks and implies a nearly exact U(2) symmetry in the first two generations, yielding a “natural SUSY” spectrum without imposing ad hoc global symmetries or giving preferential treatment to particular generations.National Science Foundation (U.S.) (NSF under grant PHY-0907744)Institute for Advanced Study (Princeton, N.J.)United States.

20024973 | 10.1007/jhep03(2013)043 | We present a fit to the 2012 LHC Higgs data in different supersymmetric frameworks using naturalness as a guiding principle. We consider the MSSM and its D-term and F -term extensions that can raise the tree-level Higgs mass. When adding an extra chiral superfield to the MSSM, three parameters are needed determine the tree-level couplings of the lightest Higgs. Two more parameters cover the most relevant loop corrections, that affect the hγγ and hgg vertexes. Motivated by this consideration, we present the results of a five parameters fit encompassing a vast class of complete supersymmetric theories. We find meaningful bounds on singlet mixing and on the mass of the pseudoscalar Higgs m [subscript A] as a function of tan β in the MSSM. We show that in the (m [subscript A] , tan β) plane, Higgs couplings measurements are probing areas of parameter space currently inaccessible to direct searches. We also consider separately the two cases in which only loop effects or only tree-level effects are sizable. In the former case we study in detail stops’ and charginos’ contributions to Higgs couplings, while in the latter we show that the data point to the decoupling limit of the Higgs sector. In a particular realization of the decoupling limit, with an approximate PQ symmetry, we obtain constraints on the heavy scalar Higgs mass in a general type-II Two Higgs Doublet Model | Fitting the Higgs to natural SUSY | fitting the higgs to natural susy | supersymmetric frameworks naturalness guiding principle. mssm extensions raise mass. adding extra chiral superfield mssm couplings lightest higgs. cover vertexes. motivated consideration encompassing vast supersymmetric theories. meaningful bounds singlet pseudoscalar subscript mssm. subscript couplings probing inaccessible searches. separately sizable. former stops’ charginos’ couplings decoupling sector. realization decoupling approximate doublet | non_dup | [] |
16413303 | 10.1007/jhep03(2013)052 | We explore the interplay between lines in the gamma-ray spectrum and LHC searches involving missing energy and photons. As an example, we consider a singlet Dirac\ud
fermion dark matter with the mediator for Fermi gamma-ray line at 130 GeV. A new chiral or local U(1) symmetry makes weak-scale dark matter natural and provides the axion or\ud
Z 0 gauge boson as the mediator connecting between dark matter and electroweak gauge bosons. In these models, the mediator particle can be produced in association with a\ud
monophoton at colliders and it produces large missing energy through the decays into a DM pair or ZZ; Z with at least one Z decaying into a neutrino pair. We adopt the monophoton searches with large missing energy at the LHC and impose the bounds on the coupling and mass of the mediator field in the models. We show that the parameter space of the Z 0 mediation model is already strongly constrained by the LHC 8TeV data, whereas a certain region of the parameter space away from the resonance in axion-like mediator models are bounded.

55632595 | 10.1007/jhep03(2013)076 | In several extensions of the Standard Model, the top quark can decay into a
bottom quark and a light charged Higgs boson H+, t → bH+, in addition to the Standard
Model decay t → bW. Since W bosons decay to the three lepton generations equally, while
H+ may predominantly decay into τν, charged Higgs bosons can be searched for using the
violation of lepton universality in top quark decays. The analysis in this paper is based on
4.6 fb−1 of proton-proton collision data at √
s = 7 TeV collected by the ATLAS experiment
at the Large Hadron Collider. Signatures containing leptons (e or µ) and/or a hadronically
decaying τ (τhad) are used. Event yield ratios between e+τhad and e+µ, as well as between
µ + τhad and µ + e, final states are measured in the data and compared to predictions from
simulations. This ratio-based method reduces the impact of systematic uncertainties in
the analysis. No significant deviation from the Standard Model predictions is observed.
With the assumption that the branching fraction B(H+ → τν) is 100%, upper limits in
the range 3.2%–4.4% can be placed on the branching fraction B(t → bH+) for charged
Higgs boson masses mH+ in the range 90–140 GeV. After combination with results from a
search for charged Higgs bosons in tt¯ decays using the τhad+jets final state, upper limits
on B(t → bH+) can be set in the range 0.8%–3.4%, for mH+ in the range 90–160 GeV.We acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWF and FWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; CONICYT, Chile; CAS, MOST and NSFC, China; COLCIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic; DNRF, DNSRC and Lundbeck Foundation, Denmark; EPLANET, ERC and NSRF, European Union; IN2P3-CNRS, CEA-DSM/IRFU, France; GNSF, Georgia; BMBF, DFG, HGF, MPG and AvH Foundation, Germany; GSRT and NSRF, Greece; ISF, MINERVA, GIF, DIP and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; FOM and NWO, Netherlands; BRF and RCN, Norway; MNiSW, Poland; GRICES and FCT, Portugal; MERYS (MECTS), Romania; MES of Russia and ROSATOM, Russian Federation; JINR; MSTD, Serbia; MSSR, Slovakia; ARRS and MVZT, Slovenia; DST/NRF, South Africa; MICINN, Spain; SRC and Wallenberg Foundation, Sweden; SER, SNSF and Cantons of Bern and Geneva, Switzerland; NSC, Taiwan; TAEK, Turkey; STFC, the Royal Society and Leverhulme Trust, United Kingdom; DOE and NSF, United States of America | Search for charged Higgs bosons through the violation of lepton universality in tt¯ events using pp collision data at s√=7 TeV with the ATLAS experiment | search for charged higgs bosons through the violation of lepton universality in tt¯ events using pp collision data at s√=7 tev with the atlas experiment | extensions boson bosons lepton generations equally predominantly bosons searched violation lepton universality decays. proton proton collision atlas hadron collider. signatures leptons hadronically decaying τhad used. τhad τhad simulations. reduces analysis. observed. branching placed branching boson gev. bosons decays τhad jets gev.we acknowledge anpcyt argentina yerphi armenia australia bmwf austria anas azerbaijan sstc belarus cnpq fapesp brazil nserc canada cern conicyt chile nsfc colciencias colombia msmt czech republic dnrf dnsrc lundbeck foundation denmark eplanet nsrf union cnrs irfu gnsf georgia bmbf foundation gsrt nsrf greece minerva benoziyo israel infn mext jsps cnrst morocco netherlands norway mnisw poland grices portugal merys mects romania russia rosatom russian federation jinr mstd serbia mssr slovakia arrs mvzt slovenia africa micinn spain wallenberg foundation sweden snsf cantons bern geneva switzerland taiwan taek turkey stfc royal leverhulme trust kingdom america | non_dup | [] |
30862355 | 10.1007/jhep03(2014)013 | A measurement of the transverse momentum spectra of jets in Pb–Pb collisions
at √sNN = 2.76TeV is reported. Jets are reconstructed from charged particles
using the anti-kT jet algorithm with jet resolution parameters R of 0.2 and 0.3 in pseudorapidity
|n| < 0.5. The transverse momentum pT of charged particles is measured down to
0.15GeV/c which gives access to the low pT fragments of the jet. Jets found in heavy-ion
collisions are corrected event-by-event for average background density and on an inclusive
basis (via unfolding) for residual background fluctuations and detector effects. A strong
suppression of jet production in central events with respect to peripheral events is observed.
The suppression is found to be similar to the suppression of charged hadrons, which suggests
that substantial energy is radiated at angles larger than the jet resolution parameter
R = 0.3 considered in the analysis. The fragmentation bias introduced by selecting jets
with a high pT leading particle, which rejects jets with a soft fragmentation pattern, has
a similar effect on the jet yield for central and peripheral events. The ratio of jet spectra
with R = 0.2 and R = 0.3 is found to be similar in Pb–Pb and simulated PYTHIA pp
events, indicating no strong broadening of the radial jet structure in the reconstructed jets

Study of Z production in PbPb and pp collisions at root s(NN)=2.76 TeV in the dimuon and dielectron decay channels. Journal of High Energy Physics(3), 40. doi:10.1007/jhep03(2015)022The production of Z bosons is studied in the dimuon and dielectron decay channels in PbPb and pp collisions at root s(NN) = 2.76TeV, using data collected by the CMS experiment at the LHC. The PbPb data sample corresponds to an integrated luminosity of about 166 mu b(-1), while the pp data sample collected in 2013 at the same nucleon-nucleon centre-of-mass energy has an integrated luminosity of 5.4 pb(-1). The Z boson yield is measured as a function of rapidity, transverse momentum, and collision centrality. The ratio of PbPb to pp yields, scaled by the number of inelastic nucleon-nucleon collisions, is found to be 1.06 +/- 0.05 (stat) +/- 0.08 (syst) in the dimuon channel and 1.02 +/- 0.08 (stat) +/- 0.15 (syst) in the dielectron channel, for centrality-integrated Z boson production. This binary collision scaling is seen to hold in the entire kinematic region studied, as expected for a colourless probe that is unaffected by the hot and dense QCD medium produced in heavy ion collisions.Additional Authors: Kiesenhofer, W.;Knunz, V.;Krammer, M.;Kratschmer, I.;Liko, D.;Mikulec, I.;Rabady, D.;Rahbaran, B.;Rohringer, H.;Schofbeck, R.;Strauss, J.;Taurok, A.;Treberer-Treberspurg, W.;Waltenberger, W.;Wulz, C.

55639313 | 10.1007/jhep03(2015)041 | A low-background inclusive search for new physics in events with same-sign dileptons is presented. The search uses proton--proton collisions corresponding to 20.3 fb−1 of integrated luminosity taken in 2012 at a centre-of-mass energy of 8 TeV with the ATLAS detector at the LHC. Pairs of isolated leptons with the same electric charge and large transverse momenta of the type e±e±,e±μ±, and μ±μ± are selected and their invariant mass distribution is examined. No excess of events above the expected level of Standard Model background is found. The results are used to set upper limits on the cross sections for processes beyond the Standard Model. Limits are placed as a function of the dilepton invariant mass within a fiducial region corresponding to the signal event selection criteria. Exclusion limits are also derived for a specific model of doubly charged Higgs boson production.We acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWF and FWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; CONICYT, Chile; CAS, MOST and NSFC, China; COLCIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic; DNRF, DNSRC and Lundbeck Foundation, Denmark; EPLANET, ERC and NSRF, European Union; IN2P3-CNRS, CEA-DSM/IRFU, France; GNSF, Georgia; BMBF, DFG, HGF, MPG and AvH Foundation, Germany; GSRT and NSRF, Greece; ISF, MINERVA, GIF, I-CORE and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; FOM and NWO, Netherlands; BRF and RCN, Norway; MNiSW and NCN, Poland; GRICES and FCT, Portugal; MNE/IFA, Romania; MES of Russia and ROSATOM, Russian Federation; JINR; MSTD, Serbia; MSSR, Slovakia; ARRS and MIZ.

78062388 | 10.1007/jhep03(2015)066 | Quiver quantum mechanics describes the low energy dynamics of a system of wrapped D-branes. It captures several aspects of single and multicentered BPS black hole geometries in four-dimensional N = 2 supergravity such as the presence of bound states and an exponential growth of microstates. The Coulomb branch of an Abelian three node quiver is obtained by integrating out the massive strings connecting the D-particles. It allows for a scaling regime corresponding to a deep AdS2 throat on the gravity side. In this scaling regime, the Coulomb branch is shown to be an SL(2, ℝ) invariant multi-particle superconformal quantum mechanics. Finally, we integrate out the strings at finite temperature — rather than in their ground state — and show how the Coulomb branch ‘melts’ into the Higgs branch at high enough temperatures. For scaling solutions the melting occurs for arbitrarily small temperatures, whereas bound states can be metastable and thus long lived. Throughout the paper, we discuss how far the analogy between the quiver model and the gravity picture, particularly within the AdS2 throat, can be taken | Conformal quivers and melting molecules | conformal quivers and melting molecules | quiver mechanics describes wrapped branes. captures multicentered geometries supergravity exponential microstates. coulomb branch abelian quiver integrating massive strings connecting particles. throat side. coulomb branch superconformal mechanics. integrate strings coulomb branch ‘melts’ branch temperatures. melting arbitrarily metastable lived. analogy quiver picture throat | non_dup | [] |
55639293 | 10.1007/jhep03(2015)088 | The results of a search for charged Higgs bosons decaying to a τ lepton and a neutrino, H±→τ±ν, are presented. The analysis is based on 19.5 fb−1 of proton--proton collision data at s√=8 TeV collected by the ATLAS experiment at the Large Hadron Collider. Charged Higgs bosons are searched for in events consistent with top-quark pair production or in associated production with a top quark. The final state is characterised by the presence of a hadronic τ decay, missing transverse momentum, b-tagged jets, a hadronically decaying W boson, and the absence of any isolated electrons or muons with high transverse momenta. The data are consistent with the expected background from Standard Model processes. A statistical analysis leads to 95% confidence-level upper limits on the product of branching ratios B(t→bH±)×B(H±→τ±ν), between 0.23% and 1.3% for charged Higgs boson masses in the range 80--160 GeV. It also leads to 95% confidence-level upper limits on the production cross section times branching ratio, σ(pp→tH±+X)×B(H±→τ±ν), between 0.76 pb and 4.5 fb, for charged Higgs boson masses ranging from 180 GeV to 1000 GeV. In the context of different scenarios of the Minimal Supersymmetric Standard Model, these results exclude nearly all values of tanβ above one for charged Higgs boson masses between 80 GeV and 160 GeV, and exclude a region of parameter space with high tanβ for H± masses between 200 GeV and 250 GeV.We acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWFW and FWF, Austria; ANAS, Azerbaijan; SSTC; Belarus; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; CONICYT, Chile; CAS, MOST and NSFC, China; COLCIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic; DNRF, DNSRC and Lundbeck Foundation, Denmark; EPLANET, ERC and NSW', :European Union; IN2P3-CNRS, GEA-DSMARFU, France; GNSF, Georgia; BMBF, :DFG, iEIGF, MPG and Avf.1 Foundation, Germany; cs-RT and INSRF; Greece; ISF, MINERVA, GW, I-CORE and Benoziyo Center, Israel; INFN, Italy; MEXT and jSPS; japan; C:NRST, Morocco; FOM: and NW, Netherlands; BRF and RCN, Norway; MNiSW and NCN, Poland; GRICES and FCT, Portugal; MNE/IFA, Romania; -NIES of Russia and ROSATOM, Russian Federation; JINR; MSTD, Serbia; MSSR; Slovakia; ARRS and MFZS, Slovenia; DST/NRF, South Africa.; MINECO, Spain; SRC and Wallenberg Foundation, Sweden; SKR, SNSF and Cantons of Bern and Geneva, Switzerland; NSC, Taiwan; TAEK, Turkey; STFC, the Royal Society and Leverhulme Trust, United Kingdom; DOE and NSF, United States of America | Search for charged Higgs bosons decaying via H± → τ±ν in fully hadronic final states using pp collision data at √s = 8 TeV with the ATLAS detector | search for charged higgs bosons decaying via h± → τ±ν in fully hadronic final states using pp collision data at √s = 8 tev with the atlas detector | bosons decaying lepton h±→τ±ν presented. proton proton collision atlas hadron collider. bosons searched quark. characterised hadronic missing tagged jets hadronically decaying boson muons momenta. processes. confidence branching t→bh± h±→τ±ν boson gev. confidence branching pp→th± h±→τ±ν boson ranging gev. scenarios supersymmetric exclude nearly tanβ boson exclude tanβ gev.we acknowledge anpcyt argentina yerphi armenia australia bmwfw austria anas azerbaijan sstc belarus cnpq fapesp brazil nserc canada cern conicyt chile nsfc colciencias colombia msmt czech republic dnrf dnsrc lundbeck foundation denmark eplanet union cnrs dsmarfu gnsf georgia bmbf ieigf avf. foundation insrf greece minerva benoziyo israel infn mext jsps nrst morocco netherlands norway mnisw poland grices portugal romania nies russia rosatom russian federation jinr mstd serbia mssr slovakia arrs mfzs slovenia africa. mineco spain wallenberg foundation sweden snsf cantons bern geneva switzerland taiwan taek turkey stfc royal leverhulme trust kingdom america | non_dup | [] |
78062390 | 10.1007/jhep03(2015)130 | We use the superconformal bootstrap to derive exact relations between OPE coefficients in three-dimensional superconformal field theories with N ≥ 4 supersymmetry. These relations follow from a consistent truncation of the crossing symmetry equations that is associated with the cohomology of a certain supercharge. In N = 4 SCFTs, the non-trivial cohomology classes are in one-to-one correspondence with certain half-BPS operators, provided that these operators are restricted to lie on a line. The relations we find are powerful enough to allow us to determine an infinite number of OPE coefficients in the interacting SCFT (U(2)[subscript 2] × U(1)[subscript −2] ABJ theory) that constitutes the IR limit of O(3) N = 8 super-Yang-Mills theory. More generally, in N = 8 SCFTs with a unique stress tensor, we are led to conjecture that many superconformal multiplets allowed by group theory must actually be absent from the spectrum, and we test this conjecture in known N = 8 SCFTs using the superconformal index. For generic N = 8 SCFTs, we also improve on numerical bootstrap bounds on OPE coefficients of short and semi-short multiplets and discuss their relation to the exact relations between OPE coefficients we derived. In particular, we show that the kink previously observed in these bounds arises from the disappearance of a certain quarter-BPS multiplet, and that the location of the kink is likely tied to the existence of the U(2)[subscript 2] × U(1)[subscript −2] AJ theory, which can be argued to not possess this multiplet.United States.

78062389 | 10.1007/jhep03(2015)133 | The scalar Higgs portal is a compelling model of dark matter (DM) in which a renormalizable coupling with the Higgs boson provides the connection between the visible world and the dark sector. In this paper we investigate the constraint placed on the parameter space of this model by the antiproton data. Due to the fact that the antiproton- to-proton ratio has relative less systematic uncertainties than the antiproton absolute flux, we propose and explore the possibility to combine all the available [bar over p]/p data. Following this approach, we are able to obtain stronger limits if compared with the existing literature. In particular, we show that most of the parameter space close to the Higgs resonance is ruled out by our analysis. Furthermore, by studying the reach of the future AMS-02 antiproton and antideuteron data, we argue that a DM mass of O(150) GeV offers a promising discovery potential. The method of combining all the antiproton-to-proton ratio data proposed in this paper is quite general, and can be straightforwardly applied to other models | Constraining the Higgs portal with antiprotons | constraining the higgs portal with antiprotons | portal compelling renormalizable boson connection visible sector. placed antiproton data. antiproton proton antiproton propose explore combine data. stronger literature. ruled analysis. studying antiproton antideuteron argue offers promising discovery potential. combining antiproton proton straightforwardly | non_dup | [] |
76177461 | 10.1007/jhep03(2016)041 | A search is performed for the production of high-mass resonances decaying into a photon and a jet in 3.2 fb−1 of proton-proton collisions at a centre-of-mass energy of s√=13 TeV collected by the ATLAS detector at the Large Hadron Collider. Selected events have an isolated photon and a jet, each with transverse momentum above 150 GeV. No significant deviation of the γ+jet invariant mass distribution from the background-only hypothesis is found. Limits are set at 95% confidence level on the cross sections of generic Gaussian-shaped signals and of a few benchmark phenomena beyond the Standard Model: excited quarks with vector-like couplings to the Standard Model particles, and non-thermal quantum black holes in two models of extra spatial dimensions. The minimum excluded visible cross sections for Gaussian-shaped resonances with width-to-mass ratios of 2% decrease from about 6 fb for a mass of 1.5 TeV to about 0.8 fb for a mass of 5 TeV. The minimum excluded visible cross sections for Gaussian-shaped resonances with width-to-mass ratios of 15% decrease from about 50 fb for a mass of 1.5 TeV to about 1.0 fb for a mass of 5 TeV. Excited quarks are excluded below masses of 4.4 TeV, and non-thermal quantum black holes are excluded below masses of 3.8 (6.2) TeV for Randall-Sundrum (Arkani-Hamed-Dimopoulous-Dvali) models with one (six) extra dimensions.We acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWFW and FWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; CONICYT, Chile; CAS, MOST and NSFC, China; COLCIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic; DNRF, DNSRC and Lundbeck Foundation, Denmark; IN2P3-CNRS, CEADSM/IRFU, France; GNSF, Georgia; BMBF, HGF, and MPG, Germany; GSRT, Greece; RGC, Hong Kong SAR, China; ISF, I-CORE and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; FOM and NWO, Netherlands; RCN, Norway; MNiSW and NCN, Poland; FCT, Portugal; MNE/IFA, Romania; MES of Russia and NRC KI, Russian Federation; JINR; MESTD, Serbia; MSSR, Slovakia; ARRS and MIZS, Slovenia; DST/NRF, South Africa; MINECO, Spain; SRC and Wallenberg Foundation, Sweden; SERI, SNSF and Cantons of Bern and Geneva, Switzerland; MOST, Taiwan; TAEK, Turkey; STFC, United Kingdom; DOE and NSF, United States of America.

76177477 | 10.1007/jhep03(2016)127 | Charged Higgs bosons heavier than the top quark and decaying via H± → tb are searched for in proton-proton collisions measured with the ATLAS experiment at s√=8 TeV corresponding to an integrated luminosity of 20.3fb−1. The production of a charged Higgs boson in association with a top quark, gb → tH±, is explored in the mass range 200 to 600 GeV using multi-jet final states with one electron or muon. In order to separate the signal from the Standard Model background, analysis techniques combining several kinematic variables are employed. An excess of events above the background-only hypothesis is observed across a wide mass range, amounting to up to 2.4 standard deviations. Upper limits are set on the gb → tH± production cross section times the branching fraction BR(H± → tb). Additionally, the complementary s-channel production, qq′ → H±, is investigated through a reinterpretation of W′ → tb searches in ATLAS. Final states with one electron or muon are relevant for H± masses from 0.4 to 2.0 TeV, whereas the all-hadronic final state covers the range 1.5 to 3.0 TeV. In these search channels, no significant excesses from the predictions of the Standard Model are observed, and upper limits are placed on the qq′ → H± production cross section times the branching fraction BR(H± → tb).We acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWFW and FWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; CONICYT, Chile; CAS, MOST and NSFC, China; COLCIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic; DNRF, DNSRC and Lundbeck Foundation, Denmark; IN2P3-CNRS, CEA-DSM/IRFU, France; GNSF, Georgia; BMBF, HGF, and MPG, Germany; GSRT, Greece; RGC, Hong Kong SAR, China; ISF, I-CORE and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; FOM and NWO, Netherlands; RCN, Norway; MNiSW and NCN, Poland; FCT, Portugal; MNE/IFA, Romania; MES of Russia and NRC KI, Russian Federation; JINR; MESTD, Serbia; MSSR, Slovakia; ARRS and MIZS, Slovenia; DST/NRF, South Africa; MINECO, Spain; SRC and Wallenberg Foundation, Sweden; SERI, SNSF and Cantons of Bern and Geneva, Switzerland; MOST, Taiwan; TAEK, Turkey; STFC, United Kingdom; DOE and NSF, United States of America.

We resolve the problem of matching with the subleading term in the strong coupling expansion of the exact gauge theory result (derived previously from localization) using a different method to compute determinants of 2d string fluctuation operators. We apply perturbation theory in a small parameter (angle of the latitude) corresponding to an expansion near the AdS 2 minimal surface representing 1/2 BPS circular Wilson loop. This allows us to compute the corrections to the heat kernels and zeta-functions of the operators in terms of the known heat kernels on AdS 2.

159621287 | 10.1007/jhep03(2017)070 | The particular structure of Galileon interactions allows for higher-derivative terms while retaining second order field equations for scalar fields and Abelian p -forms. In this work we introduce an index-free formulation of these interactions in terms of two sets of Grassmannian variables. We employ this to construct Galileon interactions for mixed-symmetry tensor fields and coupled systems thereof. We argue that these tensors are the natural generalization of scalars with Galileon symmetry, similar to p -forms and scalars with a shift-symmetry. The simplest case corresponds to linearised gravity with Lovelock invariants, relating the Galileon symmetry to diffeomorphisms. Finally, we examine the coupling of a mixed-symmetry tensor to gravity, and demonstrate in an explicit example that the inclusion of appropriate counterterms retains second order field equations | Tensor Galileons and gravity | tensor galileons and gravity | galileon retaining abelian forms. formulation grassmannian variables. employ galileon thereof. argue tensors generalization scalars galileon scalars symmetry. simplest linearised lovelock invariants relating galileon diffeomorphisms. examine inclusion counterterms retains | non_dup | [] |

The analysis is performed in the dilepton final state, characterised by the presence of two isolated leptons (electrons or muons). There are 15 observables, each sensitive to a different coefficient of the spin density matrix of t¯t production, which are measured independently. Ten of these observables are measured for the first time. All of them are corrected for detector resolution and acceptance effects back to the parton and stable-particle levels. The measured values of the observables at parton level are compared to Standard Model predictions at next-to-leading order in QCD. The corrected distributions at stable-particle level are presented and the means of the distributions are compared to Monte Carlo predictions.

143976878 | 10.1007/jhep03(2017)157 | We present charged-particle distributions sensitive to the underlying event, measured by the ATLAS detector in proton-proton collisions at a centre-of-mass energy of 13 TeV, in low-luminosity Large Hadron Collider fills corresponding to an integrated luminosity of 1.6 nb−1. The distributions were constructed using charged particles with absolute pseudorapidity less than 2.5 and with transverse momentum greater than 500 MeV, in events with at least one such charged particle with transverse momentum above 1 GeV. These distributions characterise the angular distribution of energy and particle flows with respect to the charged particle with highest transverse momentum, as a function of both that momentum and of charged-particle multiplicity.

4434393 | 10.1007/jhep04(2011)006 | The existence of a linearized SUSY invariant for N=8 supergravity whose gravitational components are usually called R[superscript 4] was established long ago by on-shell super-space arguments. Superspace and string theory methods have also established analogous higher dimensional D[superscript 2k] R[superscript 4] invariants. However, very little is known about the SUSY completions of these operators which involve other fields of the theory. In this paper we find the detailed component expansion of the linearized R[superscript 4] invariant starting from the corresponding superamplitude which generates all component matrix elements of the operator. It is then quite straightforward to extend results to the entire set of D[superscript 2k] R[superscript 4] operators.Istituto nazionale di fisica nucleare (INFN) (Bruno Rossi fellowship)National Science Foundation (U.S.) (grant PHY-0967299)United States.

78053897 | 10.1007/jhep04(2011)080 | We systematically investigate the finite set of possible gauge groups and matter content for supergravity theories in six dimensions with no tensor multiplets, focusing on nonabelian gauge groups which are a product of SU(N) factors. We identify a number of models which obey all known low-energy consistency conditions, but which have no known string theory realization. Many of these models contain novel matter representations, suggesting possible new string theory constructions. Many of the most exotic matter structures arise in models which precisely saturate the gravitational anomaly bound on the number of hypermultiplets. Such models have a rigid symmetry structure, in the sense that there are no moduli which leave the full gauge group unbroken.National Science Foundation (U.S.) ( String Vacuum Project Graduate Fellow, NSF grant PHY/0917807)National Science Foundation (U.S.) (Grant No. PHY05-51 164)United States.

143976811 | 10.1007/jhep04(2012)069 | A search is presented for same-sign top-quark production and down-type heavy quarks of charge −1/3 in events with two isolated leptons (e or μ) that have the same electric charge, at least two jets and large missing transverse momentum. The data are selected from pp collisions at √s=7TeV recorded by the ATLAS detector and correspond to an integrated luminosity of 1.04 fb−1. The observed data are consistent with expectations from Standard Model processes. Upper limits are set at 95 % confidence level on the cross section of new sources of same-sign top-quark pair production of 1.4-2.0 pb depending on the assumed mediator mass. Upper limits are also set on the pair-production cross-section for new heavy down-type quarks; a lower limit of 450 GeV is set at 95 % confidence level on the mass of heavy down-type quarks under the assumption that they decay 100 % of the time to W t.We acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN: CONICYT, Chile: CAS, MOST and NSFC, China; COLCIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic; DNRF, DNSRC and Lundbeck Foundation, Denmark; EPLANET and ERC, European Union; IN2P3-CNRS, CEA-DSM/IRFU, France; GNAS, Georgia; BMBF, DFG, HGF, MPG and AvH Foundation, Germany: GSRT, Greece; ISF, MINERVA, CIF, Center, Israel; INFN, Italy; MEXT and,JSPS Japan; CNRST, MoroccDIP and Benoziyoo; FOM and NAWO, Netherlands; RCN, Norway; MNiSW, Poland; GRICES and FCT, Portugal; MERYS (MECTS), Romania; MES of Russia and ROSATOM, Russian Federation; JINR; MSTD Serbia; MSSR, Slovakia; ARRS and MVZT, Slovenia; DST/NRF, South Africa; MICINN, Spain; SRC and Wallenberg Foundation, Sweden; SER, SNSF and Cantons of Bern and Geneva, Switzerland; NSC, Taiwan; TAEK, Turkey; STFC, the Royal Society and Leverhulme Trust, United Kingdom; DOE and NSF, United States of America.

78053866 | 10.1007/jhep04(2012)086 | Gauge/gravity duality applied to strongly interacting systems at finite density predicts a universal intermediate energy phase to which we refer as a semi-local quantum liquid. Such a phase is characterized by a finite spatial correlation length, but an infinite correlation time and associated nontrivial scaling behavior in the time direction, as well as a nonzero entropy density. For a holographic system at a nonzero chemical potential, this unstable phase sets in at an energy scale of order of the chemical potential, and orders at lower energies into other phases; examples include superconductors, and antiferromagnetic-type states. In this paper we give examples in which it also orders into Fermi liquids of “heavy” fermions. While the precise nature of the lower energy state depends on the specific dynamics of the individual system, we argue that the semi-local quantum liquid emerges universally at intermediate energies through deconfinement (or equivalently fractionalization). We also discuss the possible relevance of such a semi-local quantum liquid to heavy electron systems and the strange metal phase of high temperature cuprate superconductors.United States.

144262357 | 10.1007/jhep04(2012)124 | We present a new method to evaluate with high precision isospin breaking effects due to the small mass difference between the up and down quarks using lattice QCD. Our proposal is applicable in principle to any hadronic observable which can be computed on the lattice. It is based on the expansion of the path-integral in powers of the small parameter m(d) - m(u). In this paper, we apply this method to compute the leading isospin breaking effects for several physical quantities of interest: the kaon meson masses, the kaon decay constant, the form factors of semileptonic K-l3 decays and the neutron-proton mass splittin | Isospin breaking effects due to the up-down mass difference in lattice QCD | isospin breaking effects due to the up-down mass difference in lattice qcd | precision isospin breaking quarks qcd. proposal applicable hadronic observable lattice. powers isospin breaking quantities kaon meson kaon semileptonic decays neutron proton splittin | non_dup | [] |
55632548 | 10.1007/jhep04(2013)075 | A search for new phenomena in events with a high-energy jet and large missing transverse momentum is performed using data from proton-proton collisions at s√=7 TeV with the ATLAS experiment at the Large Hadron Collider. Four kinematic regions are explored using a dataset corresponding to an integrated luminosity of 4.7 fb−1.
