Abstract:	The production cross section of a W boson in association with two b jets is measured using a sample of proton–proton collisions at √s=8TeV collected by the CMS experiment at the CERN LHC. The data sample corresponds to an integrated luminosity of 19.8fb-1. The W bosons are reconstructed via their leptonic decays, W→ℓν, where ℓ=μ or e. The fiducial region studied contains exactly one lepton with transverse momentum pℓT>30GeV and pseudorapidity \|ηℓ\|<2.1, with exactly two b jets with pT>25GeV and \|η\|<2.4 and no other jets with pT>25GeV and \|η\|<4.7. The cross section is measured to be σ(pp→W(ℓν)+bb¯¯¯)=0.64±0.03(stat)±0.10(syst)±0.06(theo)±0.02(lumi)pb, in agreement with standard model predictions.
