The time evolution of partons that were freed after a heavy ion collision is followed through their subsequent small angle scatterings all the way to kinetic equilibrium. A Boltzmann transport equation is formulated and solved numerically, using highly anisotropic initial conditions described by the momentum scale of gluon saturation in the nuclear wavefunction. The results are shown to depend on the model used for the dynamical screening of collinear divergences. The equilibration time, the initial temperature, and the chemical potential are determined and shown to have a strong functional dependence on the initial gluon saturation scale. |
