| Abstract |
A measurement of cross sections for D* meson photoproduction at HERA is presented. The measurement uses data taken with the H1 detector during the years 1999 to 2000. The cross sections are determined in the kinematic region 171 < W < 256 GeV, Q^2 < 0.01 GeV^2, p_t(D*) > 2.5 GeV and |ta(D*)| < 1.5, where W is the photon-proton centre of mass energy and Q^2 is the photon virtuality. Photoproduction is assured through the detection of the scattered electron at small angles. In addition to the total cross section, the data are presented as a function of p_t(D*), ta(D*) and W. The results are compared to QCD predictions in leading order and next-to-leading order using collinear factorisation and to QCD predictions using k_t$-factorisation. |
