Abstract

In this contribution to the Quark Matter 2023 proceedings, we study the hydrodynamization process in heavy-ion collisions using QCD kinetic theory and introduce the new concept of limiting attractors. They are defined via an extrapolation of observables to vanishing and infinite couplings. We find that the pressure ratio exhibits both a hydrodynamic and a bottom-up limiting attractor, while the ratios of hard probes transport coefficients q^zz/q^yy and κT/κz are better described in terms of the new bottom-up limiting attractor.
