Analysis of the freeze-out parameters for RHIC, SPS and AGS based on $\frac{d{E}_T}{d\eta }/\frac{d{N}_{ch}}{d\eta }$ ratio measurements

Abstract

The ratio $\frac{d{E}_T}{d\eta }/\frac{d{N}_{ch}}{d\eta }$ 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.
