Chromodynamic corrections to neutrino production of heavy quarks

The O(α/sub s/) 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 F*2, the residual corrections to νN flavor-production structure functions are shown to be modest except for x'→1 or Q2<30 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 G→cc-bar 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
