Description
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} = 8{ {TeV}} 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→ ℓ ν , where ℓ =μ or e. The fiducial region studied contains exactly one lepton with transverse momentum pT ^{ℓ }>30 {GeV} and pseudorapidity |η ^{ℓ } |<2.1, with exactly two b jets with pT >25 {GeV} and |η |<2.4 and no other jets with pT >25 {GeV} and |η |<4.7. The cross section is measured to be σ ( pp → {W} (ℓ ν )+{{b}{overline{b}}})= 0.64 ± 0.03{ {(stat)}} ± 0.10{ {(syst)}} ± 0.06{ {(theo)}} ± 0.02{ {(lumi)}} { {pb}}, in agreement with standard model predictions.
