چکیده
The charm contribution into the proton structure function in DIS at the HERA ep-collider Abstract In the framework of perturbative QCD and a model for the production of charmed hadrons the structure function F c 2 is calculated and compared with the experimental data of H1 and ZEUS Collaborations. We show that the spectator mechanism of the D *-meson production independent of a hadronic remnant is valid at p T > 10 GeV, only. We find that the evolution of F c 2 (x, Q 2) versus the virtuality Q 2 can be neglected in the kinematic region of HERA.

متن کاملDiffractive Dijet and Charm Production at Hera
Jet and charm quark production in diffractive interactions is sensitive to the partonic structure of the diffractive exchange. This article reviews recent cross section measurements of such processes in both deep-inelastic scattering (DIS) regime and photoproduction (PHP) from the HERA ep collider experiments. The cross sections are compared to next-to-leading order QCD calculations based on fa...
متن کاملMeasurement of charm and beauty in DIS using the H 1 Vertex Detector and Combination of F cc̄ 2
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 c...
متن کاملIssues in Leading Particle and Charm Production in DIS at HERA 1
A Monte Carlo simulation based on O(αs) QCD matrix elements matched to parton showers shows that final-state hadrons in deep inelastic scattering (DIS) can be used to tag events with a single (anti)quark recoiled against the proton. The method is particularly suited to study the mean charge of leading particles, which is sensitive to fragmentation and sea quark contribution to the proton struct...
متن کاملHeavy Flavor Production at Hera
Recent results of open charm and beauty production in electron proton scattering at HERA are presented. In photoproduction, the measured cross sections for charm exceed fixed order NLO QCD calculations. Experimental evidence supports the hypothesis that a significant fraction of photoproduction events with charm can be described by resolved photon processes, where the charm quark is a constitue...
