Abstract: | It is argued that the color-averaged inclusive cross section dσ/d3p for the production of a heavy quark of given momentum p and given flavor is infrared-singularity free and therefore calculable in perturbative QCD if it is evaluated away from heavy quark thresholds and if the typical reaction energy Q is such that αs(Q)ln[Q/m(Q)] is small, αs and m being the strong coupling constant and the heavy quark mass respectively. An interpretation of this cross section is proposed in terms of heavy flavor hadronic production. |
