We simulate the space-time dynamics of high-energy collisions based on a microscopic kinetic description in the conformal relaxation time approximation, in order to determine the range of applicability of an effective description in relativistic viscous hydrodynamics. We find that hydrodynamics provides a quantitatively accurate description of collective flow when the average inverse Reynolds number is sufficiently small and the early pre-equilibrium stage is properly accounted for. We further discuss the implications of our findings for the (in)applicability of hydrodynamics in proton-proton, proton-nucleus and light nucleus collisions.

    hep-ph 2025-10 unverdicted novelty 5.0 of 10

    Minijet thermalization time in a thermal gluon plasma scales with the jet quenching parameter q-hat once recoiling medium contributions are added to standard transport coefficient definitions.

    VAH simulations in (2+1)D Bjorken flow with transverse expansion show an extended applicability domain over standard viscous hydrodynamics when compared to relaxation-time approximation kinetic theory.

    Predictions for collective flow in O-O collisions at 5.36 TeV are generated with SMASH-vHLLE hybrid, pure SMASH, and Angantyr models to probe the onset of QGP formation in small systems.
