Abstract

A scenario of heavy resonances, called massive Hagedorn states, is proposed which exhibits a fast (t ≈ 1 fm/c) chemical equilibration of (strange) baryons and anti-baryons at the QCD critical temperature T c. For relativistic heavy ion collisions this scenario predicts that hadronization is followed by a brief expansion phase during which the equilibration rate is higher than the expansion rate, so that baryons and antibaryons reach chemical equilibrium before chemical freeze-out occurs.
