Analysis of the Freeze-out Parameters for RHIC, SPS and AGS Based on  {{dET} \over {d\eta }} / {{dNch} \over {d\eta } } Ratio Measurements

Dariusz Prorok

The ratio { {dET} \over {d\eta } } / { {dNch} \over {d\eta } } is analyzed in the framework of a single-freeze-out thermal hadron gas model. Decays of hadron resonances are taken into account in evaluations of this ratio. The predictions of the model at the freeze-out parameters, established previously from observed particle yields, agree very well with the ratio measured at RHIC, SPS and AGS.
