Abstract
We consider hadron production in high energy collisions as an Unruh radiationphenomenon. This mechanism describes the production pattern of newly formedhadrons and is directly applicable at vanishing baryochemical potential, mu =0. It had already been found to correctly yield the hadronisation temperature,T_h = sqrt(sigma / 2 pi) = 165 MeV in terms of the string tension sigma. Herewe show that the Unruh mechanism also predicts hadronic freeze-out conditions,giving s/T_h^3 = 3 pi^2 / 4 = 7.4 in terms of the entropy density s and E/N =\sqrt(2 pi sigma) = 1.09 for the average energy per hadron. These predictionsprovide a theoretical basis for previous phenomenological results and are alsoin accord with recent lattice studies.
