Measurement of the D ∗ ± Meson Production Cross Section and F cc̄ 2 at High Q 2 in ep Scattering at HERA H 1 Collaboration

The inclusive production of D(2010) mesons in deep-inelastic ep scattering is measured in the kinematic region of photon virtuality 100 < Q2 < 1000GeV and inelasticity 0.02 < y < 0.7. Single and double differential cross sections for inclusive D meson production are measured in the visible range defined by |η(D∗)| < 1.5 and pT (D ) > 1.5GeV. The data were collected by the H1 experiment during the period from 2004 to 2007 and correspond to an integrated luminosity of 351 pb−1. The charm contribution, F cc̄ 2 , to the proton structure function F2 is determined. The measurements are compared with QCD predictions. Submitted to Phys. Lett.
