Total Cross Sections for Heavy Flavour Production at HERA
نویسندگان
چکیده
We compute total cross sections for charm and bottom photoproduction at HERA energies, and discuss the relevant theoretical uncertainties. In particular we discuss the problems arising from the small-x region, the uncertainties in the gluon parton density, and the uncertainties in the hadronic component of the cross section. Total electroproduction cross sections, calculated in the Weizsäcker-Williams approximation, are also given.

Heavy Flavour Production at Hera
The production of charm and beauty quarks in ep collisions at HERA has been studied by the H1 and ZEUS collaborations. Charm production is generally well described in total rate and in shape by next to leading order (NLO) calculations in perturbative quantum chromodynamics (QCD), although in specific phase space corners the NLO calculations underestimate the observed cross sections. More and mo...
متن کاملHeavy Flavour Production at Hera
A selection of topics on open heavy quark production at HERA are reviewed here. Measurements of charm fragmentation parameters will be presented together with developments in the study of D di-jet angular distributions. Charm production in deep inelastic scattering (DIS) is also discussed. Finally we deal with recent measurements of b cross sections using impact parameters in both DIS and photo...
متن کاملHeavy quark production and spectroscopy at HERA
Heavy flavour production and spectroscopy are key components of the HERA physics programme. I will summarise a selection of the recent results obtained by the H1 and ZEUS collaborations. The production of excited charm mesons and J/ψ will be discussed as well as measurements of b quark cross-sections in photoproduction. The status of searches for exotic bound states and the D∗p resonance will b...
متن کاملHeavy Flavours in Photoproduction at HERA
Differential cross sections, dσ/dx OBS γ , for dijet photoproduction events with a tagged D * meson are presented, where x OBS γ is the fraction of the photon energy contributing to the two highest transverse energy jets. Results on open beauty cross sections (from semileptonic decays) compared to LO Monte Carlo predictions are also presented. 1 Photoproduction The photon structure is being pro...
متن کاملIncluding heavy quark production in ZEUS-PDF fits
At HERA heavy quarks may contribute up to 30% of the structure function F2. The potential of including heavy-quark data in the ZEUS PDF fits is explored, using D∗ double differential cross-sections as well as the inclusive quantities F cc̄ 2 , F cc̄ 2 . The introduction of heavy quarks requires an extension of the DGLAP formalism. The effect of using different heavy flavour number schemes, and di...
