Measurement of charm and beauty in DIS using the H 1 Vertex Detector and Combination of F cc̄ 2
نویسنده
چکیده
Recent measurements by the H1 experiment of the inclusive charm and beauty cross sections in deep inelastic ep scattering at HERA are presented. The data were collected in the years 2006 and 2007 corresponding to an integrated luminosity of 189 pb −1. The numbers of charm and beauty events are determined using variables reconstructed by the H1 vertex detector. The measurement of the inclusive charm cross section is combined with the result obtained using the reconstruction of D * ± mesons in order to obtain a more precise measurement of the charm contribution F c ¯ c 2 to the proton structure function F 2. The measurements are compared with QCD predictions.

We summarize the results from the ZEUS experiment on D meson production in deep inelastic scattering using HERA I data and preliminary results on D∗± production using HERA II data. Single differential cross sections have been measured as a function of Q, x, and the transverse momentum and pseudorapidity of the D meson. These measurements are compared to the prediction of next-to-leading-order Q...

The charm and beauty production cross sections in ep neutral current processes and the charm production cross section in ep charged current processes at high Q are measured at HERA. Their determination relies on an inclusive method, where secondary decay vertices are explicitly reconstructed using the H1 vertex detector. The charm and beauty cross sections in neutral current interactions are me...
