Early time dynamics of high-energy heavy-ion collisions

Over the past decades heavy-ion experiments at RHIC and the LHC have revealed exciting properties of nuclear matter under extreme conditions, including the existence of a new state of matter, the Quark-Gluon Plasma (QGP). Strikingly, the QGP behaves as a nearly perfect fluid and effective descriptions in terms of relativistic viscous hydrodynamics have been a tremendous phenomenological success. However, understanding the dynamical origin of the observed hydrodynamic behavior represents a long standing theoretical challenge, concerning in particular the question how an equilibrated QGP liquid is created in the early stages of high-energy nuclear collisions. Following a short introduction to the physics of high-energy heavy-ion collisions, I will discuss recent theoretical progress in understanding the early time non-equilibrium dynamics from the point of collision to the formation of a hydrodynamic liquid. Specifically, I will describe how a consistent description of this pre-equilibrium stage can be achieved by a combination of weak-coupling methods and present first applications of this framework to studies of collective flow.
