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