A parton cascade calculation of heavy quark production and collective flow effects in the QGP — •Jan Uphoff, Oliver Fochler, Zhe Xu, and Carsten Greiner — Institut für Theoretische Physik, Goethe-Universität, Frankfurt am Main

We investigate heavy quark production and space-time evolution in heavy-ion collisions at RHIC energy with the partonic transport model BAMPS. The heavy quark yield from primary hard collisions between partons of the nuclei is obtained using the Monte Carlo event generator PYTHIA, comparing various parton distribution functions. Secondary production via g+g → c+c and the evolution of heavy quarks are studied within a fully dynamic BAMPS simulation for central Au+Au collisions at RHIC energy. We estimate kinetic and chemical equilibration times in box calculations and then compare them to the relevant time scales in the QGP. Furthermore, we throw a first glance on collective flow and energy loss of heavy quarks.
