The HERA-B experiment has collected data on proton-induced collisions with three fixed nuclear targets at 41.6 GeV centre-of-mass energy. Preliminary results of an ongoing, detailed study of charmonium production include the determination of the nuclear dependence of the J/ฯ production kinematics (e

The results on charm production at HERA are reviewed. The data are compared with next-to-leading order (NLO) perturbative QCD predictions. In photoproduction the measured differential cross sections are generally larger than the NLO calculations, in particu]ar in the forward (proton) direction. The
On behalf of the Hl and ZEUS Collaborations Inclusive charm meson production cross sections in the deep inelastic scattering and photoproduction regimes are compared with QCD leading and next-to-leading order (NLO) calculations. The NLO predictions are significantly below the data in some parts of
