Abstract (data abstract)
CERN-LHC. The paper presents measurements of the associated production of a W boson and a charm-quark jet (W + c) in pp collisions at a center-of-mass energy of 7 TeV. The analysis is conducted with a data sample corresponding to a total integrated luminosity of 5 fb^-1, collected in 2011 by the CMS detector at the LHC. W boson candidates are identified by their decay into a charged lepton (muon or electron) and a neutrino. The W + c measurements are performed for charm-quark jets in the kinematic region pT(jet) > 25 GeV, |eta(jet)| < 2.5, for two different thresholds for the transverse momentum of the lepton from the W-boson decay, and in the pseudorapidity range |eta(lepton)| < 2.1. Hadronic and inclusive semileptonic decays of charm hadrons are used to measure the total cross sections and cross section ratios. Cross sections and cross section ratios are also measured differentially with respect to the absolute value of the pseudorapidity of the lepton from the W-boson decay.
