We present a measurement of the cross section for W boson production in association with at least one b-quark jet in proton–antiproton collisions. The measurement is made using data corresponding to an integrated luminosity of 6.1 fb−1 recorded with the D0 detector at the Fermilab Tevatron View the MathML source Collider at View the MathML source. We measure an inclusive cross section of View the MathML source and View the MathML source in the phase space defined by View the MathML source, View the MathML source, |ηb-jet|<1.1, and a muon (electron) with View the MathML source and |ημ|<1.7 (|ηe|<1.1 or 1.5<|ηe|<2.5). The combined result per lepton family is View the MathML source for |ηℓ|<1.7. The results are in agreement with predictions from next-to-leading order QCD calculations using mcfm, View the MathML source, and also with predictions from the sherpa and madgraph Monte Carlo event generators.
