Solution of the Boltzmann Equation for Gluons after a Heavy Ion Collision

A non-linear Boltzmann equation¹ describing the time evolution of a partonic system in the central rapidity region after a heavy ion collision is solved numerically². A particular model of the collinear logarithmic divergences due to small angle scattering^3,4 is employed in the numerical solution. The system is followed until it reaches kinetic equilibrium where the equilibration time, temperature and chemical potential are determined for both RHIC and LHC.
