Description
Inclusive production of D*+- -mesons in deep inelastic scattering at HERA is studied at high photon virtualities Q2>100 GeV^2 for the first time with the H1 experiment. The data were collected during the years 2004-2007 and correspond to an integrated luminosity of 351 pb^-1. D*-mesons are reconstructed in their decays D*+- -> D0+ pi_slow+- -> K-+ pi+- pi_slow+-. The visible range for the measurement covers the pseudorapidity interval |eta(D*)|<1.5, transverse momenta p_T(D*)>1.5 GeV, and inelasticity in the scattering process 0.02 < y < 0.7. Differential cross sections are compared to predictions from the next-to leading order calculation HVQDIS and the leading order Monte Carlo codes RAPGAP and CASCADE.
