| Abstract: The production cross section of the W boson in association with two b jets is measured using a sample of proton-proton collisions collected by the CMS experiment at the LHC at $\sqrt{s} =$ 8 TeV. The data sample corresponds to an integrated luminosity of 19.8 fb$^{-1}$. The W bosons are reconstructed via their leptonic decays to muons ($\mathrm{W}\rightarrow\mu\nu$) and electrons ($\mathrm{W}\rightarrow\mathrm{e}\nu$). The $\mathrm{ W+b \bar{b} }$ production cross section, $\sigma ( \mathrm{ pp \rightarrow W (\ell\nu)+ b \bar{b} })= $ 0.69 $\pm$ 0.02 (stat) $\pm$ 0.11 (syst) $\pm$ 0.07 (theo) $\pm$ 0.02 (lumi) pb, measured in a fiducial region, $p_T^{\ell}>$ 30 GeV, $|\eta^{\ell}| <$ 2.1, with exactly two b-tagged jets having $p_{\mathrm{T}} >$ 25 GeV and $|\eta|<$ 2.4 , agrees with standard model predictions. | ||
