Recent Developments in Heavy Flavour Production
نویسنده
چکیده
We review one-particle inclusive production of heavy-flavoured hadrons in a framework which resums the large collinear logarithms through the evolution of the FFs and PDFs and retains the full dependence on the heavy-quark mass without additional theoretical assumptions. We focus on presenting results for the inclusive cross section for the production of charmed mesons in pp̄ collisions and the comparison with CDF data from the Tevatron as well as on inclusive B-meson production and comparison with recent CDF data. The third topic is the production of D mesons in photoproduction and comparison with recent H1 data from HERA.

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 کاملRecent experimental results in heavy flavour production at HERA
A review of recent results involving heavy flavour production at the electron-proton collider HERA is presented. The role which heavy flavour production plays in the understanding of photon and proton structure is emphasised, indicating the areas in which further experimental data and the further development of theoretical calculations will be of particular benefit.
متن کاملHeavy Flavour Production
I review recent developements in the theory of heavy flavour production. In particular, I dicuss the next-to-leading resummation of soft gluon effects in heavy flavour hadroproduction, and the next-to-leading resummation of collinear radiation in the production of heavy flavour at large transverse momenta. 1 Talk presented at the 12 Rencontre de Physique de la Valle d’Aoste, La Thuile, March 19...
متن کامل2002 Heavy Flavour Production ∗
Recent progress in Heavy Flavour Production phenomenology are discussed. In particular, the long-standing discrepancy of the Tevatron b production data is considered. It is shown that a better use of e + e − data in constraining the effect of fragmentation reduces the discrepancy considerably.
