Production of heavy quarks in hadron-hadron collisions — •Johann Riedl, Marco Stratmann, and Andreas Schäfer — Universität Regensburg, 93040 Regensburg

The production of heavy quarks in polarised proton-proton collisions at BNL-RHIC is one of the processes which can give information about the currently largely unconstrained gluon polarisation Δ g in the nucleon. For this purpose the calculation of the relevant cross sections in next-to-leading order of QCD perturbation theory is presented. The difference of the differential cross sections for the production of heavy quarks and antiquarks, the so-called charge asymmetry, is directly sensitive to next-to-leading order corrections. Phenomenological studies for BNL-RHIC, LHC and TeVatron are given.
