Event-by-event Kinetic Description of Pre-Equilibrium Charge Evolution in QCD Plasma

Abstract

We use QCD effective kinetic theory to calculate far-from-equilibrium dynamics on an event-by-event basis within the Kø{}MPø{}ST framework. We present non-equilibrium charge response functions and the dynamical evolution of the conserved charge current pertinent to the early-time dynamics of heavy-ion collisions at the highest energies. The Kø{}MPø{}ST framework with conserved baryon, strangeness, and electric charges can then be readily implemented into a multistage model allowing for the initialization of a non-equilibrium charge current in hydrodynamic simulations.
