| Abstract |
D* mu coincidences are studied using data taken with the H1 detector at HERA during the years 1997 to 2000, corresponding to an integrated luminosity of about 90 pb^-1. With the aid of charge and angle correlations between the D* and the muon, a separation of charm and beauty production is possible. Measurements are performed of the total charm and beauty production cross sections in the kinematical region pt(D*) < 1.5 GeV, |eta(D*)|<1.5, pt(mu) >1.0 GeV, |eta(mu)| < 1.74 and 0.05 < y < 0.75, where pt (eta) denote the tranverse momentum (pseudorapidity) of the D* meson and the muon. Differential cross sections of several D* mu quantities are compared with the prediction of Leading Order (LO) Monte Carlo, e.g. the squared transverse momentum of the D* mu pair. |
