We present the next-to-leading order QCD corrections to the production
of a W-boson in association with a jet containing a heavy quark. The
calculation is fully differential in the final state particle moments
and includes the mass of the heavy quark. We study for the case of the
Tevatron the sensitivity of the cross section to the strange quark di
stribution function, the dependence of the cross section on the heavy
quark mass, the transverse momentum distribution of the jet containing
the heavy quark, and the momentum distribution of the heavy quark in
the jet.
