Perturbative QCD predictions for inclusive production of heavy mesons ine+eannihilation

Abstract
Within the framework of a particular model for meson production, we have performed a perturbative QCD analysis for inclusive production of heavy mesons D, B, and T at an energy range of 20110 GeV. At the high-energy limit, analytic calculations of total cross sections, fragmentation functions, and angular distributions are presented. For T mesons, all mass terms in the leading-order perturbative calculation are included in numerical estimates. We found these terms give 2030% corrections for D- and B-meson production at √s ∼60 GeV. The forward-backward asymmetry from weak-electromagnetic interference is found to be large at KEK TRISTAN energy.
