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 Q 2<2 GeV2 and photon–proton centre-of-mass energies of 100<W γp <285 GeV. Inclusive D ∗ meson differential cross sections are measured for central rapidities |η(D ∗)|<1.5 and transverse momenta p T (D ∗)>1.8 GeV. The heavy quark production process is further investigated in events with at least two jets with transverse momentum p T (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 p T (D ∗)>2.1 GeV. The results are compared with predictions from Monte Carlo simulations and next-to-leading order perturbative QCD calculations. Show more
