Abstract

Measurements are presented of inclusive charm and beauty cross sections in e+p collisions at HERA for values of photon virtuality Q2 > 150 GeV2 and of inelasticity 0.1 < y < 0.7. The charm and beauty fractions are determined using a method based on the impact parameter, in the transverse plane, of tracks to the primary vertex, as measured by the H1 vertex detector. The data are divided into four regions in Q2 and Bjorken x, and values for the structure functions Fc¯c 2 and Fb¯b 2 are obtained. The results are found to be compatible with the predictions of perturbative quantum chromodynamics.
