Thermal hadron production in high energy heavy ion collisions

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

We provide a method to test if hadrons produced in high energy heavy ion collisions were emitted at freeze-out from an equilibrium hadron gas. Our considerations are based on an ideal gas at fixed temperatureT f , baryon number densityn B , and vanishing total strangeness. The constituents of this gas are all hadron resonances up to a mass of 2 GeV; they are taken to decay according to the experimentally observed branching ratios. The ratios of the various resulting hadron production rates are tabulated as functions ofT f andn B . These tables can be used for the equilibration analysis of any heavy ion data; we illustrate this for some specific cases.
