Search for supersymmetry in pp collisions at √s = 8 TeV in events with a single lepton, large jet multiplicity, and multiple b jets
Results are reported from a search for supersymmetry in pp collisions at a center-of-mass energy of 8 TeV, based on events with a single isolated lepton (electron or muon) and multiple jets, at least two of which are ...
Studies of azimuthal dihadron correlations in ultra-central PbPb collisions at √sNN =2.76 TeV
Azimuthal dihadron correlations of charged particles have been measured in PbPb collisions at √sNN = 2.76TeV by the CMS collaboration, using data from the 2011 LHC heavy-ion run. The data set includes a sample of ultra-central ...
Observation of a peaking structure in the J/ψφ mass spectrum from B±→J/ψφK± decays
A peaking structure in the J/ψφ mass spectrum near threshold is observed in B± → J/ψφK± decays, produced in pp collisions at √s = 7 TeV collected with the CMS detector at the LHC. The data sample, selected on the basis ...
Study of double parton scattering using W + 2-jet events in proton-proton collisions at √s = 7 TeV
Double parton scattering is investigated in proton-proton collisions at √s = 7 TeV where the final state includes a W boson, which decays into a muon and a neutrino, and two jets. The data sample corresponds to an integrated ...
Measurements of the tt̄ charge asymmetry using the dilepton decay channel in pp collisions at √s = 7 TeV
The tt̄ charge asymmetry in proton-proton collisions at √s = 7 TeV is measured using the dilepton decay channel (ee, eμ, or μμ). The data correspond to a total integrated luminosity of 5.0 fb−1, collected by the CMS ...
Measurement of the production cross section for a W boson and two b jets in pp collisions at √s=7 TeV
The production cross section for a W boson and two b jets is measured using proton–proton collisions at √s = 7 TeV in a data sample collected with the CMS experiment at the LHC corresponding to an integrated luminosity ...
