A Study of Parton Energy Loss in Au+Au Collisions at RHIC using Transport Theory
Y. Nara, S. E. Vance, P. Csizmadia
Abstract
Parton energy loss in Au+Au collisions at RHIC energies is studied by numerically solving the relativistic Boltzmann equation for the partons including 2 2 and 2 2 + final state radiation collision processes. Final particle spectra are obtained using two hadronization models; the Lund string fragmentation and independent fragmentation models. Recent, preliminary π0 transverse momentum distributions from central Au+Au collisions at RHIC are reproduced using gluon-gluon scattering cross sections of 5-12 mb, depending upon the hadronization model. Comparisons with the HIJING jet quenching algorithm are made.
