Towards a Unified Understanding of Jet Quenching and Elliptic Flow within a Perturbative QCD Parton Transport

The gluonic contribution to the nuclear modification factor RAA is investigated for central Au+Au collisions at √(s)=200 AGeV employing a perturbative QCD-based parton cascade including radiative processes. A flat quenching pattern is found up to transverse momenta of 30 GeV, which is slightly smaller compared with results from the Gyulassy-Levai-Vitev formalism. We demonstrate that the present microscopic transport description provides a challenging means of investigating both jet quenching and a strong buildup of elliptic flow in terms of the same standard perturbative QCD interactions.
