Phenomenological 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.
متن کاملDijet angular distributions in photoproduction of charm at HERA
Dijet angular distributions of photoproduction events in which a D meson is produced in association with one of two energetic jets have been measured with the ZEUS detector at HERA, using an integrated luminosity of 120 pb. Differential cross sections as a function of the angle between the charm-jet and the proton-beam direction in the dijet rest frame have been measured for samples enriched in...
متن کاملDirect Gluon Density Determination in Tagged Charm-photoproduction at Hera
Charm production at HERA is dominated by events with a very small virtuality of the exchanged photon photoproduction In lowest order it proceeds via photon gluon fusion and is therefore directly sensitive to the gluon density in the proton In this thesis single inclusive D spectra in and pt are measured in photopro duction at W p GeV and W p GeV and the energy ow in these charm events is analys...
متن کاملJet photoproduction at HERA
We compute various kinematical distributions for one-jet and two-jet inclusive photoproduction at HERA. Our results are accurate to next-to-leading order in QCD. We use the subtraction method for the cancellation of infrared singularities. We perform a thorough study of the reliability of QCD predictions; in particular, we consider the scale dependence of our results and discuss the cases when ...
