dc.description.abstract
Relativistic heavy-ion collisions are used to study the high-temperature properties of QCD at large particle colliders (LHC, RHIC) and allow us to probe the non-equilibrium properties of the Quark-Gluon Plasma (QGP) created therein. The non-equilibrium initial stages and the approach to hydrodynamics are commonly studied using QCD kinetic theory. Despite its success, all current implementations rely on approximations of the hard thermal loop (HTL) screened matrix element in the scattering processes. In my talk, I will show how to relax some currently used approximations. I will introduce limiting attractors, which we obtain by extrapolating our results to vanishing and strong couplings. The strong coupling limit is identified with a hydrodynamic attractor, whereas the weak coupling limit corresponds to the time scale in the perturbative "bottom-up" thermalization scenario. While both of these attractors are visible in the pressure ratio, I will also discuss these attractors in quantities measuring the momentum broadening of hard probes such as jets and heavy quarks, which admit a good description in terms of the weak coupling limiting attractor.
