Description
The quark gluon plasma thermalization in heavy ion collisions is an open problem that gave rise to many works in recent years. One of the approaches developped to study this QCD non pertubative problem is a resummation scheme that amounts to averaging over classical fields with random initial conditions. Its numerical implementation is presented here in the case of a scalar field theory with a quartic coupling, that shares some important features with QCD (scale invariance at the classical level and the presence of instabilities). In particular, we will show the relevance of this resummation in capturing the physics relevant for thermalization.
