Abstract
The perturbative quantum-chromodynamic corrections to weak, charged-current production of heavy quarks are evaluated. For perturbative subtractions and parton densities defined via the electroproduction structure function , the residual corrections to flavor-production structure functions are shown to be modest except for or . We investigate sensitivity of the results to different perturbative subtraction prescriptions. Specializing to charm production, we further find that, for GeV, color-radiative corrections modify estimated production cross sections by no more than 10%. The results for charm are shown to be generally insensitive to factorization of splitting "singularities" into evolution of an intrinsic charm-sea component of the nucleon. The longitudinal structure function due to charm production is computed and found to be substantial.
