dc.description.abstract	The production cross section for a W boson and two b jets is measured using proton–proton collisions at vs=7TeV 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>25GeV 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→μν) ×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.	es_ES
