Abstract
Inclusive photoproduction of D(+)/- in ep collisions at HERA has been measured with the ZEUS detector for photon-proton centre of mass ener gies in the range 115 < W < 280 GeV and photon virtuality Q(2) < 4 GeV 2. The cross section sigma(ep) --> DX integrated over the kinematic r egion p(D)(perpendicular to) 3 GeV acid -1.5 < eta(D)* < 1.0 is (10.6 +/- 1.7(stat.)+/-(1.6)(1.3)(syst.)) nb. Differential cross sections a s functions of p(D)(perpendicular to), eta(D)* and W are given. The d ata are compared with two next-to-leading order perturbative QCD predi ctions. For a calculation using a massive charm scheme the predicted c ross sections are smaller than the measured ones. A recent calculation using a massless charm scheme is in agreement with the data.
