Results on charm photoproduction at HERA are presented. The inclusive photoproduction of D' mesons has been measured using 1996/97 data samples with an integrated luminosity of 37pb-'. Differential cross sections as function of the D' transverse momentum and pseudorapidity are compared with next-to-

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
