Charged-Current Leptoproduction of D-Mesons in the Variable Flavor Scheme
S. Kretzer, I. Schienbein
Abstract
We present formulae for the momentum (z) distributions of D-mesons produced in neutrino deep-inelastic scattering off strange partons. The expressions are derived within the variable flavor scheme of Aivazis et al. (ACOT-scheme), which is extended from its fully inclusive formulation to one-hadron inclusive leptoproduction. The dependence of the results on the assumed strange quark mass ms is investigated and the m 0 limit is compared to the corresponding MSbar results. The importance of O(alphas) quark-initiated corrections is demonstrated for the ms=0 case.
