Abstract
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 of 5.0 fb^(−1). The W + bb events are selected in the W → μν decay mode by requiring a muon with transverse momentum p_T>25 GeV and pseudorapidity |η|<2.1, and exactly two b-tagged jets with p_T>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.

We congratulate our colleagues in the CERN accelerator departments for the excellent performance of the LHC and thank the technical and administrative staffs at CERN and at other CMS institutes for their contributions to the success of the CMS effort. In addition, we gratefully acknowledge the computing centers and personnel of the Worldwide LHC Computing Grid for deliv-ering so effectively the computing infrastructure essential to our analyses.
