Abstract

The inclusive photoproduction of D mesons and of D-tagged dijets is investigated with the H1 detector at the ep collider HERA. The kinematic region covers small photon virtualities Q2<2 GeV2 and photon–proton centre-of-mass energies of 100<Wγp<285 GeV. Inclusive D meson differential cross sections are measured for central rapidities |η(D)|<1.5 and transverse momenta pT(D)>1.8 GeV. The heavy quark production process is further investigated in events with at least two jets with transverse momentum pT(jet)>3.5 GeV each, one containing the D meson. Differential cross sections for D-tagged dijet production and for correlations between the jets are measured in the range |η(D)|<1.5 and pT(D)>2.1 GeV. The results are compared with predictions from Monte Carlo simulations and next-to-leading order perturbative QCD calculations.
