Title: Non-equilibrium QCD in Heavy-Ion collisions
Abstract
Over the past decades, experiments at the Relativistic Heavy-Ion Collider (RHIC) and the Large Hadron Collider (LHC) have collected an overwhelming amount of evidence of the formation of a de-confined Quark-Gluon Plasma (QGP) , and established a standard picture of the space-time evolution of the QGP based on relativistic viscous hydrodynamics. While high-energy Heavy-Ion Collisions thus provide a unique laboratory to study strong-interaction matter under extreme conditions, it has proven challenging to understand how the far-from equilibrium initial state eventually turns into a nearly equilibrated plasma of quarks and gluons. In this talk I will highlight recent theoretical progress in understanding different thermalization mechanisms in QCD plasmas and address the question how an almost equilibrated Quark-Gluon plasma is created during the early stages of high-energy collisions. I will also discuss how these studies provide new insights into the range of applicability of dissipative fluid dynamics and the emergence of universal properties in out-of-equilibrium systems, and if time remains address some phenomenological consequences of the early time non-equilibrium dynamics.
