Title Chemical equilibration in hadronic collisions
Abstract We study chemical equilibration in out-of-equilibrium Quark-Gluon Plasma using the first principle method of QCD effective kinetic theory, accurate at weak coupling. In longitudinally expanding systems---relevant for relativistic nuclear collisions---we find that for realistic couplings chemical equilibration takes place after hydrodynamization, but well before local thermalization. We estimate that hadronic collisions with final state multiplicities $dNch/d \eta > \sim 102$ live long enough to reach approximate chemical equilibrium, which is consistent with the saturation of strangeness enhancement observed in proton-proton, proton-nucleus and nucleus-nucleus collisions. \\ \\ References: arXiv:1811.03040, arXiv:1811.03068
