dc.description.abstractThe 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 of 5.0 fb−1. The W + bb events are selected in the W → μν decay mode by requiring a muon with transverse momentum pT > 25 GeV and pseudorapidity |η| < 2.1, and exactly two b-tagged jets with pT > 25 GeV and |η| < 2.4. The measured W + bb production cross section in the fiducial region, calculated at the level of final-state particles, is σ(pp → W + bb) × B(W → μν) = 0.53 ± 0.05 (stat.) ± 0.09 (syst.) ± 0.06 (theo.) ± 0.01 (lum.) pb, in agreement with the standard model prediction. In addition, kinematic distributions of the W + bb system are in agreement with the predictions of a simulation using MadGraph and pythia.en_US
