Measurement of the cross-section for W boson production in association with b-jets in pp collisions at s = 7 TeV with the ATLAS detector

Popis výsledku v původním jazyce

This paper reports a measurement of the W+b-jets (W+b+X and W+bb? +X) production cross-section in proton-proton collisions at a centre-of-mass energy of 7 TeV at the LHC. These results are based on data corresponding to an integrated luminosity of 4.6 fb1, collected with the ATLAS detector. Cross-sections are presented as a function of jet multiplicity and of the transverse momentum of the leading b-jet for both the muon and electron decay modes of the W boson. The W+b-jets cross-section, corrected forall known detector eects, is quoted in a limited kinematic range. Combining the muon and electron channels, the ducial cross-section for W+b-jets is measured to be 7.1 0.5 (stat) 1.4 (syst) pb, consistent with the next-to-leading order QCD prediction, corrected for non-perturbative and double-parton interactions (DPI) contributions, of 4.7 0.09 (stat) +0.600.49 (scale) 0.06 (PDF) 0.16 (non-pert) +0.520.38 (DPI) pb.
