MEASUREMENT OF CHARM PRODUCTION IN DEEP INELASTIC SCATTERING WITH THE ZEUS DETECTOR

摘要

We present measurements of charm production in DIS using the ZEUS detector. Data with ∫ Ldt = 83 pb~(-1) have been analysed. For the channel D~(*+) → D~0π_s~+ →K~-π~+π_s~+ (+c.c.) a cross section has been extracted, differential in the kinematical variables Q~2 and Bjorken x. In addition the decay cq → e~- v_eX has been studied in a data sample of ∫ Ldt = 34 pb~(-1). This results in a cross section, differential in O~2, x and W of the event and in P_T and η of the decay electron. The structure function F_2~(cc) has also been determined for this channel. All measured cross sections show good agreement with NLO pQCD predictions from HVQDIS.
