Nonequilibrium thermodynamics: a powerful tool for scientists and engineers
(2012)DYNAWe present the two-generator framework of nonequilibrium thermodynamics with a strong emphasis on fundamental notions rather than mathematical details. The underlying statistical mechanics and the implications for thermodynamically guided simulation techniques are sketched briefly. The usefulness and maturity of the framework are illustrated by reviewing a large number of recent far-from-equilibrium applications, where nonlinearity ...Journal Article -
Neuroenhancement - perspectives of Swiss psychiatrists and general practitioners
(2012)Swiss Medical WeeklyQUESTIONS UNDER STUDY: Although the ethical and health implications of neuroenhancement have been intensely discussed over the past years, little is known about the experiences and attitudes of physicians confronted with requests for neuroenhancing substances. The aim of this study was to explore general practitioners’ and psychiatrists’ familiarity with such requests and their willingness to prescribe these products. METHOD: A nation-wide ...Journal Article -
Search for large extra dimensions in dimuon and dielectron events in pp collisions at root s=7 TeV
(2012)Physics Letters BResults are presented from a search for large, extra spatial dimensions in events with either two isolated muons or two isolated electrons. The data are from proton–proton interactions at √s=7TeV collected with the CMS detector at the LHC. The size of the data sample corresponds to an integrated luminosity of approximately 2fb-1 . The observed dimuon and dielectron mass spectra are found to be consistent with standard-model expectations. ...Journal Article -
Measurement of the charge asymmetry in top-quark pair production in proton-proton collisions at root s=7 TeV
(2012)Physics Letters BThe difference in angular distributions between top quarks and antiquarks, commonly referred to as the charge asymmetry, is measured in pp collisions at the LHC with the CMS experiment. The data sample corresponds to an integrated luminosity of 1.09fb -1 at a centre-of-mass energy of 7 TeV. Top-quark pairs are selected in the final state with an electron or muon and four or more jets. At least one jet is identified as originating from ...Journal Article -
Search for charge-asymmetric production of W′ bosons in top pair + jet events from pp collisions at √s = 7 TeV
(2012)Physics Letters BA search is presented for charge-asymmetric production of a W' boson that has been proposed to accommodate the forward-backward asymmetry observed in the production of top-antitop quark pairs at the Tevatron. The new heavy W' boson would be produced in association with a top quark and would decay into top and down quarks. The data correspond to an integrated luminosity of 5.0 fb(-1) in pp collisions at a center-of-mass energy of 7 TeV, ...Journal Article -
Search for neutral Higgs bosons decaying to tau pairs in pp collisions at sqrt(s)=7 TeV
(2012)Physics Letters BA search for neutral Higgs bosons decaying to tau pairs at a center-of-mass energy of 7 TeV is performed using a dataset corresponding to an integrated luminosity of 4.6 fb−1 recorded by the CMS experiment at the LHC. The search is sensitive to both the standard model Higgs boson and to the neutral Higgs bosons predicted by the minimal supersymmetric extension of the standard model (MSSM). No excess of events is observed in the tau-pair ...Journal Article -
Search for three-jet resonances in pp collisions at √s=7 TeV
(2012)Physics Letters BResults are reported from a search for the production of three-jet resonances in pp collisions at a center-of-mass energy √s=7 TeV. The study uses the data sample collected by the CMS experiment at the LHC in 2011, corresponding to an integrated luminosity of 5.0fb-1. Events with high jet multiplicity and a large scalar sum of jet transverse momenta are analyzed for the presence of resonances in the three-jet invariant mass spectrum. No ...Journal Article -
Search for the standard model Higgs boson decaying to bottom quarks in pp collisions at sqrt(s)=7 TeV
(2012)Physics Letters BA search for the standard model Higgs boson (H) decaying to (b) over barb when produced in association with weak vector bosons (V) is reported for the following modes: W(mu nu)H, W(e nu)H, Z(mu mu)H, Z(ee)H and Z(nu nu)H. The search is performed in a data sample corresponding to an integrated luminosity of 4.7 fb(-1), recorded by the CMS detector in proton-proton collisions at the LHC with a center-of-mass energy of 7 TeV. No significant ...Journal Article -
Search for the standard model Higgs boson decaying to W+W− in the fully leptonic final state in pp collisions at √ s = 7 TeV
(2012)Physics Letters BA search for the standard model Higgs boson decaying to W +W - in pp collisions at s=7 TeV is reported. The data are collected at the LHC with the CMS detector, and correspond to an integrated luminosity of 4.6 fb -1. The W +W - candidates are selected in events with two charged leptons and large missing transverse energy. No significant excess of events above the standard model background expectations is observed, and upper limits on the ...Journal Article -
Study of W boson production in PbPb and pp collisions at √s[NN] = 2.76 TeV
(2012)Physics Letters BA measurement is presented of W-boson production in PbPb collisions carried out at a nucleon-nucleon (NN) centre-of-mass energy root S-NN of 2.76 TeV at the LHC using the CMS detector. In data corresponding to an integrated luminosity of 7.3 mu b(-1), the number of W -> mu v(mu) decays is extracted in the region of muon pseudorapidity vertical bar eta mu vertical bar < 2.1 and transverse momentum p(T)(mu) > 25 GeV/c. Yields of muons found ...Journal Article
