Abstract

Inclusive photoproduction of D(+/-) mesons has been measured for photon-proton centre-of-mass energies in the range 130 < W < 280GeV and photon virtuality Q(2) < 1 GeV2. The data sample used corresponds to anintegrated luminosity of 37 pb(-1). Total and differential cross sections as functions of the D transverse momentum and pseudorapidity arepresented in restricted kinematical regions and the data are comparedwith next-to-leading order (NLO) perturbative QCD calculations using the ''massive charm'' and ''massless charm'' schemes. The measured cross sections are generally above the NLO calculations, in particular inthe forward (proton) direction. The large data sample also allows thestudy of dijet production associated with charm. A significant resolved as well as a direct photon component contribute to the cross section. Leading order QCD Monte Carlo calculations indicate that the resolved contribution arises from a significant charm component in the photon. A massive charm NLO parton level calculation yields lower cross sections compared to the measured results in a kinematic region where theresolved photon contribution is significant.
