Search for anomalous Wtb couplings and flavour-changing neutral currents in t-channel single top quark production in pp collisions at root s=7 and 8 TeV
(Springer International, 2017)
Single top quark events produced in the t channel are used to set limits on anomalous Wtb couplings and to search for top quark flavour-changing neutral current (FCNC) interactions. The data taken with the CMS detector at ...
The CMS trigger system
(IOP , 2017)
This paper describes the CMS trigger system and its performance during Run 1 of the LHC. The trigger system consists of two levels designed to select events of potential physics interest from a GHz (MHz) interaction rate ...
Search for CP violation in t(t)over-bar production and decay in proton-proton collisions at root s=8 TeV
(Springer International, 2017)
The results of a first search for CP violation in the production and decay of top quark-antiquark ( tt¯tt¯ ) pairs are presented. The search is based on asymmetries in T-odd, triple-product correlation observables, where ...
Evidence for collectivity in pp collisions at the LHC
(Elsevier, 2017)
Measurements of two- and multi-particle angular correlations in pp collisions at View the MathML source are presented as a function of charged-particle multiplicity. The data, corresponding to integrated luminosities of ...
Search for heavy neutrinos or third-generation leptoquarks in final states with two hadronically decaying tau leptons and two jets in proton-proton collisions at root s=13 TeV
(Springer International, 2017)
A search for new particles has been conducted using events with two high transverse momentum (pT) τ leptons that decay hadronically, at least two high-pT jets, and missing transverse energy from the τ lepton decays. The ...
Suppression and azimuthal anisotropy of prompt and nonprompt J/psi production in PbPb collisions at root S-NN=2.76 TeV
(Springer International Publishing, 2017-04)
The nuclear modification factor R-AA and the azimuthal anisotropy coefficient v(2) ofprompt and nonprompt (i.e. those from decays of b hadrons) J/psi mesons, measured from PbPb and pp collisions at root S-NN = 2.76 rfeV ...
Charged-particle nuclear modification factors in PbPb and pPb collisions at root s(NN)=5.02 TeV
(Springer International Publishing, 2017)
The spectra of charged particles produced within the pseudorapidity window |η| < 1 at sNN−−−−√=5.02sNN=5.02 TeV are measured using 404 μb−1 of PbPb and 27.4 pb−1 of pp data collected by the CMS detector at the LHC in ...
Measurement and QCD analysis of double-differential inclusive jet cross sections in pp collisions at root s=8 TeV and cross section ratios to 2.76 and 7 TeV
(Springer International Publishing, 2017)
A measurement of the double-differential inclusive jet cross section as a function of the jet transverse momentum pT and the absolute jet rapidity |y| is presented. Data from LHC proton-proton collisions at s√=8s=8 TeV, ...
Search for supersymmetry in events with one lepton and multiple jets in proton-proton collisions at √s=13TeV
(American Physical Society, 2017-01-27)
A search for supersymmetry is performed in events with a single electron or muon in proton-proton collisions at a center-of-mass energy of 13 TeV. The data were recorded by the CMS experiment at the LHC and correspond to ...
Search for electroweak production of charginos in final states with two T leptons in pp collisions at root s=8 TeV
(Springer International Publishing, 2017-04-04)
Results are presented from a search for the electroweak production of supersymmetric particles in pp collisions in final states with two τ leptons. The data sample corresponds to an integrated luminosity between 18.1 fb−1 ...
