Abstract

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 p¯p √ Collider at s = 1.96 TeV. We measure an inclusive cross section of σ(W(→μν) + b + X) = 1.04 ± 0.05 (stat.) ± 0.12 (syst.) pb and σ(W(→eν)+b+ X) = 1.00±0.04 (stat.)±0.12 (syst.) pb in the phase space defined by pνT > 25 GeV, pb-jet T > 20 GeV,
