Production via top decay is not included in the signal definition. The measurement is based on 35 pb(-1) of data collected with the ATLAS detector at the LHC. The W + b-jet cross section is defined for jets reconstructed with the anti-k(t) clustering algorithm with transverse momentum above 25 GeV and rapidity within +/-2.1. The b-jets are identified by reconstructing secondary vertices. The fiducial cross section is measured both for the electron and muon decay channel of the W boson and is found to be 10.2 +/- 1.9(stat) +/- 2.6(syst) pb for one lepton flavour. The results are compared with next-to-leading order QCD calculations, which predict a cross section smaller than, though consistent with, the measured value.", optnote="WOS:000300211000002", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=917), last updated on Fri, 16 Mar 2012 16:44:24 +0000", issn="0370-2693", doi="10.1016/j.physletb.2011.12.046", opturl="http://arxiv.org/abs/1109.1470", opturl="https://doi.org/10.1016/j.physletb.2011.12.046", archivePrefix="arXiv", eprint="1109.1470", language="English" }
