Measurement of the production cross section of a W boson in association with two b jets in pp collisions at root s=8TeV

Original language 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 root 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 -&gt; l(v) where l = mu or e. The fiducial region studied contains exactly one lepton with transverse momentum pT(l) &gt; 30 GeV and pseudorapidity |eta(l)| &lt; 2.1, with exactly two b jets with pT &gt; 25 GeV and |eta(l)| &lt; 2.4 and no other jets with pT &gt; 25 GeV and |eta(l)| &lt; 4.7. The cross section is measured to be sigma(pp -&gt; W(lv)+b&lt;(b)over bar&gt;) = 0.64 +/- 0.03 (stat) +/- 0.10 (syst) +/- 0.06 (theo) +/- 0.02 (lumi) pb, in agreement with standard model predictions.
