Search for squarks and gluinos in events with isolated leptons, jets and missing transverse momentum at â\u88\u9as = 8 TeV with the ATLAS detector

Â© 2015, The Author(s).The results of a search for supersymmetry in final states containing at least one isolated lepton (electron or muon), jets and large missing transverse momentum with the ATLAS detector at the Large Hadron Collider are reported. The search is based on proton-proton collision data at a centre-of-mass energy â\u88\u9a = 8 TeV collected in 2012, corresponding to an integrated luminosity of 20 fb<sup>â\u88\u921</sup>. No significant excess above the Standard Model expectation is observed. Limits are set on supersymmetric particle masses for various supersymmetric models. Depending on the model, the search excludes gluino masses up to 1.32 TeV and squark masses up to 840 GeV. Limits are also set on the parameters of a minimal universal extra dimension model, excluding a compactification radius of 1/R<inf>c</inf> = 950 GeV for a cut-off scale times radius (Î\u9bR<inf>c</inf>) of approximately 30
Search for direct chargino production in anomaly-mediated supersymmetry breaking models based on a disappearing-track signature in pp collisions at $\sqrt{s}$=7 TeV with the ATLAS detector

A search for direct chargino production in anomaly-mediated supersymmetry breaking scenarios is performed in pp collisions at $\sqrt{s}$ = 7 TeV using 4.7 fb$^{-1}$ of data collected with the ATLAS experiment at the LHC. In these models, the lightest chargino is predicted to have a lifetime long enough to be detected in the tracking detectors of collider experiments. This analysis explores such models by searching for chargino decays that result in tracks with few associated hits in the outer region of the tracking system. The transverse-momentum spectrum of candidate tracks is found to be consistent with the expectation from the Standard Model background processes and constraints on chargino properties are obtained
Measurement of the cross-section for W boson production in association with b-jets in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

This paper reports a measurement of the W+b-jets (W+b+X and W+b (b) over bar +X) production cross-section in proton-proton collisions at a centre-of-mass energy of 7 TeV at the LHC. These results are based on data corresponding to an integrated luminosity of 4.6 fb(-1), collected with the ATLAS detector. Cross-sections are presented as a function of jet multiplicity and of the transverse momentum of the leading b-jet for both the muon and electron decay modes of the W boson. The W+b-jets cross-section, corrected for all known detector effects, is quoted in a limited kinematic range. Combining the muon and electron channels, the fiducial cross-section for W+b-jets is measured to be 7.1 +/- 0.5 (stat) +/- 1.4 (syst) pb, consistent with the next-to-leading order QCD prediction, corrected for non-perturbative and double-parton interactions (DPI) contributions, of 4.70 +/- 0.09 (stat) (+0.60)(-0.49) (scale) +/- 0.06 (PDF) +/- 0.16 (non-pert) (+0.52)(-0.38) (DPI) pb
The baryonic tully-fisher relationship for S4G galaxies and the "condensed" baryon fraction of galaxies

We combine data from the Spitzer Survey for Stellar Structure in Galaxies, a recently calibrated empirical stellar mass estimator from Eskew et al., and an extensive database of H i spectral line profiles to examine the baryonic Tully–Fisher (BTF) relation. We find (1) that the BTF has lower scatter than the classic Tully–Fisher (TF)  relation and is better described as a linear relationship,   confirming similar previous results, (2) that the inclusion          of a radial scale in the BTF decreases the scatter but only modestly, as seen previously for the TF relation, and (3) that the slope of the BTF, which we find to be 3.5 ± 0.2 (Δ log Mbaryon/Δ log v_c), implies that on average a nearly constant fraction (∼0.4) of all baryons expected to be in a alo are “condensed” onto the central region of rotationally supported galaxies. The condensed baryon fraction, M_baryon/M_total, is, to our measurement precision, nearly independent of galaxy circular velocity (our sample spans circular velocities, v_c, between 60 and 250 km s^−1, but is extended to v_c ∼ 10 km s^−1 using data from the literature). The observed galaxy-to-galaxy scatter in this fraction is generally ≤a factor of 2 despite fairly liberal selection criteria. These results imply that cooling and heating processes, such as cold versus hot accretion, mass loss due to stellar winds, and active galactic nucleus driven feedback, to the degree that they affect the global galactic properties involved in the BTF, are independent of halo mass for galaxies with 10 < vc < 250 km s^−1 and typically introduce no more than a factor of two range in the resulting M_baryon/M_total. Recent simulations by Aumer et al. of a small sample of disk galaxies are in excellent agreement with our data, suggesting that current simulations are capable of reproducing the global properties of individual disk galaxies. More detailed comparison to models using the BTF holds great promise, but awaits improved determinations of the stellar masses
Scaling self-similar formulation of the string equations of the hermitian one-matrix model

The string equation appearing in the double scaling limit of the Hermitian one–matrix model, which corresponds to a Galilean self–similar condition for the KdV hierarchy, is reformulated as a scaling self–similar condition for the Ur–KdV hierarchy. A non– scaling limit analysis of the one–matrix model has led to the complexified NLS hierarchy and a string equation. We show that this corresponds to the Galilean self– similarity condition for the AKNS hierarchy and also its equivalence to a scaling self– similar condition for the Heisenberg ferromagnet hierarchy
Tracing kinematic (mis)alignments in CALIFA merging galaxies. Stellar and ionized gas kinematic orientations at every merger stage

We present spatially resolved stellar and/or ionized gas kinematic properties for a sample of 103 interacting galaxies, tracing all merger stages: close companions, pairs with morphological signatures of interaction, and coalesced merger remnants. In order to distinguish kinematic properties caused by a merger event from those driven by internal processes, we compare our galaxies with a control sample of 80 non-interacting galaxies. We measure for both the stellar and the ionized gas components the major (projected) kinematic position angles (PA_kin, approaching and receding) directly from the velocity distributions with no assumptions on the internal motions. This method also allow us to derive the deviations of the kinematic PAs from a straight line (δPA_kin). We find that around half of the interacting objects show morpho-kinematic PA misalignments that cannot be found in the control sample. In particular, we observe those misalignments in galaxies with morphological signatures of interaction. On the other hand, the level of alignment between the approaching and receding sides for both samples is similar, with most of the galaxies displaying small misalignments. Radial deviations of the kinematic PA orientation from a straight line in the stellar component measured by δPA_kin are large for both samples. However, for a large fraction of interacting galaxies the ionized gas δPA_kin is larger than the typical values derived from isolated galaxies (48%), indicating that this parameter is a good indicator to trace the impact of interaction and mergers in the internal motions of galaxies. By comparing the stellar and ionized gas kinematic PA, we find that 42% (28/66) of the interacting galaxies have misalignments larger than 16 degrees, compared to 10% from the control sample. Our results show the impact of interactions in the motion of stellar and ionized gas as well as the wide the variety of their spatially resolved kinematic distributions. This study also provides a local Universe benchmark for kinematic studies in merging galaxies at high redshift
Modelling the enigmatic Late Pliocene Glacial Event: Marine Isotope Stage M2

The Pliocene Epoch (5.2 to 2.58Ma) has often been targeted to investigate the nature ofwarmclimates. However,\ud
climate records for the Pliocene exhibit significant variability and show intervals that apparently experienced a\ud
cooler than modern climate. Marine Isotope Stage (MIS) M2 (~3.3 Ma) is a globally recognisable cooling event\ud
that disturbs an otherwise relatively (compared to present-day) warm background climate state. It remains\ud
unclear whether this event corresponds to significant ice sheet build-up in the Northern and Southern\ud
Hemisphere. Estimates of sea level for this interval vary, and range from modern values to estimates of 65 m\ud
sea level fall with respect to present day. Here we implement plausibleM2 ice sheet configurations into a coupled\ud
atmosphere–ocean climate model to test the hypothesis that larger-than-modern ice sheet configurations may\ud
have existed at M2. Climate model results are compared with proxy climate data available for M2 to assess the\ud
plausibility of each ice sheet configuration. Whilst the outcomes of our data/model comparisons are not in all\ud
cases straight forward to interpret, there is little indication that results from model simulations in which\ud
significant ice masses have been prescribed in the Northern Hemisphere are incompatible with proxy data from\ud
the North Atlantic, Northeast Arctic Russia, North Africa and the Southern Ocean. Therefore, our model results do\ud
not preclude thepossibilityof the existenceof larger icemasses duringM2 in the Northern or SouthernHemisphere.\ud
Specifically they are not able to discount the possibility of significant icemasses in the Northern Hemisphere during\ud
the M2 event, consistent with a global sea-level fall of between 40 m and 60 m. This study highlights the general\ud
need for more focused and coordinated data generation in the future to improve the coverage and consistency in\ud
proxy records for M2, which will allow these and future M2 sensitivity tests to be interrogated further
Search for third-generation scalar leptoquarks in the t$\tau$ channel in proton-proton collisions at $\sqrt{s}=8$

A search for pair production of third-generation scalar leptoquarks decaying to top quark and $\tau$ lepton pairs is presented using proton-proton collision data at a center-of-mass energy of $\sqrt{s}=8 TeV$ collected with the CMS detector at the LHC and corresponding to an integrated luminosity of 19.7 $fb^{−1}$. The search is performed using events that contain an electron or a muon, a hadronically decaying τ lepton, and two or more jets. The observations are found to be consistent with the standard model predictions. Assuming that all leptoquarks decay to a top quark and a τ lepton, the existence of pair produced, charge −1/3, third-generation leptoquarks up to a mass of 685 GeV is excluded at 95% confidence level. This result constitutes the first direct limit for leptoquarks decaying into a top quark and a $\tau$ lepton, and may also be applied directly to the pair production of bottom squarks decaying predominantly via the R-parity violating coupling $\lambda_{333}'$
Deep inelastic scattering structure functions of holographic spin-1 hadrons with N f ≥ 1

Two-point current correlation functions of the large N limit of supersymmetric and non-supersymmetric Yang-Mills theories at strong coupling are investigated in terms of their string theory dual models with quenched flavors. We consider non-Abelian global symmetry currents, which allow one to investigate vector mesons with N f > 1. From the correlation functions we construct the deep inelastic scattering hadronic tensor of spin-one mesons, obtaining the corresponding eight structure functions for polarized vector mesons. We obtain several relations among the structure functions. Relations among some of theirmoments are also derived. Aspects of the sub-leading contributions in the 1 /N and N f /N expansions are discussed. At leading order we find a universal behavior of the hadronic structure functions
One-loop W L W L and Z L Z L scattering from the electroweak Chiral Lagrangian with a light Higgs-like scalar

By including the recently discovered Higgs-like scalar φ in the Electroweak Chiral Lagrangian, and using the Equivalence Theorem, we carry out the complete one-loop computation of the elastic scattering amplitude for the longitudinal components of the gauge bosons V = W , Z at high energy. We also compute φφ → φφ and the inelastic process VV → φφ , and identify the counterterms needed to cancel the divergences, namely the well known a 4 and a 5 chiral parameters plus three additional ones only superficially treated in the literature because of their dimension 8. Finally we compute all the partial waves and discuss the limitations of the one-loop computation due to only approximate unitarity
Vortex zero modes, large flux limit and Ambjørn-Nielsen-Olesen magnetic instabilities

In the large flux limit vortices become flux tubes with almost constant magnetic field in the interior region. This occurs in the case of non-Abelian vortices as well, and the study of such configurations allows us to reveal a close relationship between vortex zero modes and the gyromagnetic instabilities of vector bosons in a strong background magnetic field discovered by Nielsen, Olesen and Ambjørn. The BPS vortices are exactly at the onset of this instability, and the dimension of their moduli space is precisely reproduced in this way. We present a unifying picture in which, through the study of the linear spectrum of scalars, fermions and W bosons in the magnetic field background, the expected number of translational, orientational, fermionic as well as semilocal zero modes is correctly reproduced in all cases
Addendum to “Leptogenesis in an SU(5)×A5 golden ratio flavour model” [Nucl. Phys. B 896 (2015) 311–329]

We derive and discuss the solution of the Boltzmann equations for leptogenesis in a phenomenologically viable SU(5)×A5 golden ratio flavour model proposed in [1,2] . The model employs, in particular, the seesaw mechanism of neutrino mass generation. We find that the results on the baryon asymmetry of the Universe, obtained earlier in [2] using approximate analytic expressions for the relevant CP violating asymmetry and efficiency factors, are correct, as was expected, up to 20–30%. The phenomenological predictions for the low energy neutrino observables, derived using values of the parameters of the model for which we reproduce the observed value of the baryon asymmetry, change little with respect to those presented in [2] . Among the many predictions of the model we find, for instance, that the neutrinoless double beta decay effective Majorana mass mee lies between 3.3 meV and 14.3 meV
Quasifission and difference in formation of evaporation residues in the
  $^{16}$O+$^{184}$W and $^{19}$F+$^{181}$Ta reactions

The excitation functions of capture, complete fusion, and evaporation residue
formation in the $^{16}$O+$^{184}$W and $^{19}$F+$^{181}$Ta reactions leading
to the same $^{200}$Pb compound nucleus has been studied theoretically to
explain the experimental data showing more intense yield of evaporation residue
in the former reaction in comparison with that in the latter reaction. The
observed difference is explained by large capture cross section in the former
and by increase of the quasifission contribution to the yield of fission-like
fragments in the $^{19}$F+$^{181}$Ta reaction at large excitation energies. The
probability of compound nucleus formation in the $^{16}$O+$^{184}$W reaction is
larger but compound nuclei formed in both reactions have similar angular
momentum ranges at the same excitation energy. The observed decrease of
evaporation residue cross section normalized to the fusion cross section in the
$^{19}$F+$^{181}$Ta reaction in comparison with the one in the
$^{16}$O+$^{184}$W reaction at high excitation energies is explained by the
increase of hindrance in the formation of compound nucleus connected with more
quick increase of the quasifission contribution in the $^{19}$F induced
reaction. The spin distributions of the evaporation residue cross sections for
the two reactions are also presented

Developing clinical scenarios from a European perspective: Successes and challenges.

This paper presents developmental work involving students from the University College Dublin (UCD), Ireland (n=9), University of Surrey, England (n=8) and University of Ljubljana and University of Maribor, Slovenia (n=5) participating in the Erasmus Intensive Programme. The Erasmus programme offers a two week 'Summer School' in the Faculty of Health Sciences, University of Maribor, Slovenia. Using a participatory approach, facilitators from both the UCD and Surrey engaged with students from all of the universities to develop scenarios for simulated learning experiences, in the care of older people, for utilisation on an e learning facility and within the simulated clinical learning environment. Students developed key transferable skills in learning, such as information literacy, cultural diversity, team working, communication, and clinical skills acquisition whilst exploring differences in healthcare delivery in other European countries
The Campi Flegrei caldera: unrest mechanisms and hazards

In the last four decades, Campi Flegrei caldera has been the world’s most active
caldera characterized by intense unrest episodes involving huge ground deformation and
seismicity, but, at the time of writing, has not culminated in an eruption. We present a careful
review, with new analyses and interpretation, of all the data and recent research results. We
deal with three main problems: the tentative reconstruction of the substructure; the modelling
of unrest episodes to shed light on possible pre-eruptive scenarios; and the probabilistic
estimation of the hazards from explosive pyroclastic products. The results show, for the first
time at a volcano, that a very peculiar mechanism is generating episodes of unrest, involving
mainly activation of the geothermal system from deeper magma reservoirs. The character and
evolution of unrest episodes is strongly controlled by structural features, like the ring-fault
system at the borders of the caldera collapse. The use of detailed volcanological, mathematical
and statistical procedures also make it possible to obtain a detailed picture of eruptive hazards
in the whole Neapolitan area. The complex behaviour of this caldera, involving interaction
between magmatic and geothermal phenomena, sheds light on the dynamics of the most
dangerous types of volcanoes in the world
Randomized trial of complete versus lesion-only revascularization in patients undergoing primary percutaneous coronary intervention for STEMI and Multivessel Disease

BACKGROUND: The optimal management of patients found to have multivessel disease while undergoing primary percutaneous coronary intervention (P-PCI) for ST-segment elevation myocardial infarction is uncertain. OBJECTIVES: CvLPRIT (Complete versus Lesion-only Primary PCI trial) is a U.K. open-label randomized study comparing complete revascularization at index admission with treatment of the infarct-related artery (IRA) only. METHODS: After they provided verbal assent and underwent coronary angiography, 296 patients in 7 U.K. centers were randomized through an interactive voice-response program to either in-hospital complete revascularization (n = 150) or IRA-only revascularization (n = 146). Complete revascularization was performed either at the time of P-PCI or before hospital discharge. Randomization was stratified by infarct location (anterior/nonanterior) and symptom onset (≤3 h or >3 h). The primary endpoint was a composite of all-cause death, recurrent myocardial infarction (MI), heart failure, and ischemia-driven revascularization within 12 months. RESULTS: Patient groups were well matched for baseline clinical characteristics. The primary endpoint occurred in 10.0% of the complete revascularization group versus 21.2% in the IRA-only revascularization group (hazard ratio: 0.45; 95% confidence interval: 0.24 to 0.84; p = 0.009). A trend toward benefit was seen early after complete revascularization (p = 0.055 at 30 days). Although there was no significant reduction in death or MI, a nonsignificant reduction in all primary endpoint components was seen. There was no reduction in ischemic burden on myocardial perfusion scintigraphy or in the safety endpoints of major bleeding, contrast-induced nephropathy, or stroke between the groups. CONCLUSIONS: In patients presenting for P-PCI with multivessel disease, index admission complete revascularization significantly lowered the rate of the composite primary endpoint at 12 months compared with treating only the IRA. In such patients, inpatient total revascularization may be considered, but larger clinical trials are required to confirm this result and specifically address whether this strategy is associated with improved survival.

Invariant template matching in systems with spatiotemporal coding: A matter of instability

We consider the design principles of algorithms that match templates to images subject to spatiotemporal encoding. Both templates and images are encoded as temporal sequences of samplings from spatial patterns. Matching is required to be tolerant to various combinations of image perturbations. These include ones that can be modeled as parameterized uncertainties such as image blur, luminance, and, as special cases, invariant transformation groups such as translation and rotations, as well as unmodeled uncertainties (noise). For a system to deal with such perturbations in an efficient way, they are to be handled through a minimal number of channels and by simple adaptation mechanisms. These normative requirements can be met within the mathematical framework of weakly attracting sets. We discuss explicit implementation of this principle in neural systems and show that it naturally explains a range of phenomena in biological vision, such as mental rotation, visual search, and the presence of multiple time scales in adaptation. We illustrate our results with an application to a realistic pattern recognition problem
