Abstract

We present a measurement of the cross sections for the associated production of a W boson with at least one heavy quark jet, b or c , in proton–antiproton collisions. Data corresponding to an integrated luminosity of 8.7 fb−1 recorded with the D0 detector at the Fermilab Tevatron View the MathML source Collider at View the MathML source are used to measure the cross sections differentially as a function of the jet transverse momenta in the range 20 to 150 GeV. These results are compared to calculations of perturbative QCD theory as well as predictions from Monte Carlo generators. Measurement of the production cross section of a W boson in association with a b or c-quark jet provides a stringent test of quantum chromodynamics (QCD). At hadron colliders, the associated production of a heavy quark with a W boson can also be a significant background to rare standard model (SM) processes, for example, production of top quark pairs [1], a single top quark [2], and a W boson in association with a Higgs boson decaying to two b quarks [3], as well as for new physics processes, e.g., supersymmetric scalar top quark production [4].
