Extraction of kinetic freeze-out properties and effect of resonance decays
/ Authors
/ 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 parametrization and statistical model. We discuss the effect of resonance decays on the extracted kinetic freeze-out parameters.
