Heavy Quark Production in Hadronic Collisions
We review the physics of heavy quark and quarkonium production in high energy hadronic collisions. We discuss the status of the theoretical calculations and compare the current results with the most recent measurements from the Tevatron collider experiments. CERN-TH/95-191 July 1995 To appear in the Proceedings of the 6th International Symposium on Heavy Flavour Physics, Pisa, Italy, June 6-10,...
متن کاملHEAVY QUARK PRODUCTION IN pp COLLISIONS
A systematic study of the inclusive single heavy quark and heavy-quark pair production cross sections in pp collisions is presented for RHIC and LHC energies. We compare with existing data when possible. The dependence of the rates on the renormalization and factorization scales is discussed. Predictions of the cross sections are given for two di erent sets of parton distribution functions. Dep...
متن کاملHeavy Quark Production in Γγ Collisions
Heavy quark production in γγ collisions has recently received increased theoretical attention 1,2,3 motivated in part by new experimental data on cc and bb production from LEP2 (see 4 for references). Although the data on bb production have sizable errors and the theoretical predictions suffer from uncertainties, the excess by a factor of about three of the data over theoretical predictions rep...
متن کاملHeavy quark production in γγ collisions revisited
Heavy quark production in γγ collisions is reanalyzed. It is argued that evaluating the cross section σ(γγ → QQ) in a well-defined renormalization scheme requires the inclusion of direct photon contributions up to the order α 2 α 2 s. The order α 2 α 2 s direct photon contributions are furthermore needed for factorization scale invariance of the sum of direct and resolved photon contributions. ...
متن کاملHeavy quark production in γγ collisions: a theoretical reappraisal
Heavy quark production in γγ collisions is analyzed within the approach to hard collisions of photons recently proposed by the author. In this approach evaluating the cross section σ(γγ → QQ) in the “next–to–leading order of QCD” requires the inclusion of direct photon contributions up to the order αα s, whereas in the standard approach direct photon terms only up to the order ααs are taken int...
