dc.description.abstractThe 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 19.8 fb-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 predictionsen_US
