The production of heavy quarks at large \pt (\pt≫ m) in hadronic collisions is considered. The analysis is carried out in the framework of perturbative fragmentation functions, thereby allowing a resummation at the NLO level of final state large mass logarithms of the kind log(\pt/m). The case of b-quark production is considered in detail. The resulting theoretical uncertainty from factorization/renormalization scales at large \pt is found to be much smaller than that shown by the full O(\as3) perturbative calculation.
