We examine the possibility of distinguishing between different parametrizations of the photon parton densities using charm production data, and the possibility of extracting information about the small-x behaviour of the gluon density of the proton.

Abstract

We compute pseudorapidity and transverse momentum distributions for charm and bottom production at HERA. We examine the effect of next-to-leading order QCD corrections, the effect of possible intrinsic transverse momenta of the incoming partons, and of fragmentation. We compare our results with those of a full Monte Carlo simulation using HERWIG. The importance of the hadronic component of the photon is also studied. We examine the possibility of distinguishing between different parametrizations of the photon parton densities using charm production data, and the possibility of extracting information about the small-x behaviour of the gluon density of the proton. We also give a prediction for the transverse momentum and pseudorapidity distributions for bottom production at HERA.
