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

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