Chiral condensate in a hadron resonance gas and a model for chemical freeze-out

The derivation of a formula for the chiral condensate in a hadron resonance gas is presented. A model for chemical freeze-out is presented where the melting of the chiral condensate in hot, dense hadronic matter leads to an increase in the hadronic radii facilitating fast chemical equilibration. The model predictions are in agreement with recent results from the beam energy scan program of the STAR experiment at RHIC Brookhaven.
