Abstract
We consider the transverse-momentum distribution of heavy flavours in photo n-hadron collisions. We present a formalism in which large transverse-momen tum logarithms are resummed to the next-to-leading level, and mass effects are included exactly up to order alpha (em)alpha (2)(s), so as to retain pr edictivity at both small and large transverse momenta. Phenomenological app lications relevant to charm photoproduction at HERA are given.
