Measurement of the charm fragmentation function in D photoproduction at HERA
The charm fragmentation function has been measured in D photoproduction with the ZEUS detector at HERA using an integrated luminosity of 120 pb. The fragmentation function is measured versus z = (E + p‖) D∗/2Ejet, where E is the energy of the D meson and p‖ is the longitudinal momentum of the D meson relative to the axis of the associated jet of energy E. Jets were reconstructed using the kT cl...
متن کاملCharm fragmentation at HERA
Recent data on charm fragmentation, collected and analyzed by the H1 and ZEUS collaborations, are reviewed and compared with a results from e + e − experiments. The measured fragmentation ratios and fragmentation fractions are in agreement with those measured in e + e − , thus supporting the assumption of universality. Results on the structure of charm jets are presented. The normalized differe...
متن کاملMeasurement of charm fragmentation ratios and fractions in photoproduction at HERA
The production of D, D, D, D s and Λ + c charm hadrons and their antiparticles in ep scattering at HERA was measured with the ZEUS detector using an integrated luminosity of 79 pb. The measurement has been performed in the photoproduction regime with the exchanged-photon virtuality Q < 1GeV and for photon-proton centre-of-mass energies in the range 130 < W < 300GeV. The charm hadrons were recon...
متن کاملPhenomenological study of charm photoproduction at HERA
We present predictions for single inclusive distributions of charmed mesons, relevant to the HERA experiments. Our results are based upon a computation that correctly incorporates mass effects up to the next-to-leading order level, and the resummation of transverse momentum logarithms up to next-to-leading-logarithmic level. We apply the same acceptance cuts as the H1 and Zeus experiments, and ...
متن کاملDiffractive charm photoproduction at HERA ep - collider
The cross section of the D *-meson diffractive photoproduction at the HERA collider has been calculated in the framework of perturbatively motivated model for the different kine-matic regions. The camparison between the different Pomeron models has been performed.
