Hadroproduction of D and B mesons in a massive VFNS

Abstract

We present a calculation of the next-to-leading order cross section for the inclusive hadroproduction of D and B mesons as a function of the transverse momentum and the rapidity in a massive variable flavor number scheme. We compare our numerical results with recent data from the CDF Collaboration at the Fermilab Tevatron for the production of D^0, D^{*+}, D^+, and D_s^+ mesons at center-of-mass energy $\sqrt{S}=1.96$ TeV and find reasonably good agreement with the measured cross sections.
