Production and Thermal Equilibration of Partons in Relativistic Heavy Ion Collisions: s= 20 vs. 200 A GeV
Abstract
The production and thermalization of partons liberated in relativistic heavy ioncollisions is investigated within the parton cascade model. The momentum distribution of the partons near z=0 is found to become isotropic beyond about 1 fm/c after the overlap for the collision of lead nuclei at s=20 A GeV indicating a thermalization. At s=200 A GeV this is attained by about 0.5 fm/c after the complete overlap.
