Description

Initial state of heavy ion collision and subsequent hydrodynamic evolution are separated by a short phase of fast equilibration of underlying degrees of freedom. We use effective kinetic theory, accurate at weak coupling, to simulate the pre-equilibrium evolution of transverse energy and flow perturbations. We construct a Green function which propagates the initial perturbations to the energy-momentum tensor at a time when hydrodynamics becomes applicable.
This allows the complete pre-thermal evolution from saturated nuclei to hydrodynamics to be modelled in a perturbatively controlled way.
