Search for supersymmetry in events with one lepton and multiple jets in proton-proton collisions at s =13 TeV
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 ...
Measurements of the tt¯ production cross section in lepton+jets final states in pp collisions at 8 TeV and ratio of 8 to 7 TeV cross sections
A measurement of the top quark pair production (tt¯) cross section in proton–proton collisions at the centre-of-mass energy of 8TeV is presented using data collected with the CMS detector at the LHC, corresponding to an ...
Measurement of the t t ¯ production cross section using events in the e μ final state in pp collisions at √s=13 TeV
The cross section of top quark–antiquark pair production in proton–proton collisions at s=13TeV is measured by the CMS experiment at the LHC, using data corresponding to an integrated luminosity of 2.2fb-1. The measurement ...
Charged-particle nuclear modification factors in PbPb and pPb collisions at √sNN=5.02 TeV
The spectra of charged particles produced within the pseudorapidity window |η| < 1 at sNN=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 2015. The spectra ...
Measurement of the WZ production cross section in pp collisions at √s=7 and 8 TeV and search for anomalous triple gauge couplings at √s=8TeV
The WZ production cross section is measured by the CMS experiment at the CERN LHC in proton–proton collision data samples corresponding to integrated luminosities of 4.9fb-1 collected at s=7TeV, and 19.6fb-1 at s=8TeV. The ...
Study of Jet Quenching with Z+jet Correlations in Pb-Pb and pp Collisions at s NN=5.02 TeV
The production of jets in association with Z bosons, reconstructed via the μ+μ- and e+e- decay channels, is studied in pp and, for the first time, in Pb-Pb collisions. Both data samples were collected by the CMS experiment ...
