Extraction of Kinetic Freeze-out Properties and Effect of Resonance Decays
Abstract
We present STAR results from identified particle spectra measured in $\sqrt{s_{NN}}$ = 62.4 GeV Au-Au collisions. Particle production and system dynamics are compared to results at $\sqrt{s_{NN}}$ = 200 GeV. We extract kinetic and chemical freeze-out parameters using blast wave model parameterization and statistical model. We discuss the effect of resonance decays on the extracted kinetic freeze-out parameters.
