We consider the transverse-momentum distribution of heavy flavours in hadronic collisions. We present a formalism in which large transverse-momentum logarithms are resummed at the next-to-leading level, and mass effects are included exactly up to order alpha(s)(3), so as to retain predictivity at both small and large transverse momenta. As an example, we apply our formalism to b production at the Tevatron

Abstract

We present a formalism in which large transverse-momentum logarithms are resummed at the next-to-leading level, and mass effects are included exactly up to order alpha(s)(3), so as to retain predictivity at both small and large transverse momenta.
