Description

When and to what extent a thermalized Quark Gluon Plasma is achieved in heavy-ion collision impacts the quantitative extraction of transport properties in the QGP. We address this problem by employing the largest to date real time classical-statistical lattice simulations. Most remarkably, we find that the thermalization process is governed by a universal attractor, where the space-time evolution of the plasma becomes independent of the initial conditions [1,2]. In this classical regime, the plasma exhibits the self-similar dynamics characteristic of wave turbulence, as observed in a large variety of strongly correlated many-body systems. We interpret the consequences of our numerical lattice results for thermalization in heavy-ion experiments. [1] J.Berges,K.Boguslavski,S.Schlichting,R.Venugopalan; arXiv:1303.5650 [hep-ph].
