Analysis of the freeze-out parameters for RHIC, SPS and AGS based on ${{dE_{T}} \over {d\eta}} / {{dN_{ch}} \over {d\eta}}$ ratio measurement

In the presented paper ${{dE_{T}} \over {d\eta}} / {{dN_{ch}} \over {d\eta}}$ ratio 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 the ratio. The predictions of the model at the freeze-out parameters previously established from observed particle yields agree very well with the ratio measured at RHIC, SPS and AGS.
