QCD plasma thermalization, collective flow and extraction of shear viscosity
arXiv:0807.2986 · doi:10.1088/0954-3899/35/10/104016
Abstract
Fast thermalization and elliptic flow of QCD matter found at the Relativistic Heavy Ion Collider (RHIC) are understood as the consequence of perturbative QCD (pQCD) interactions within a (3+1) dimensional parton cascade. The main contributions stem from pQCD-inspired bremsstrahlung. We extract the shear viscosity to entropy ratio, which is between 0.08 and 0.15.
