A comparison of statistical hadronization models
Giorgio Torrieri, Johann Rafelski
Abstract
We investigate the sensitivity of fits of hadron spectra produced in heavy ion collisions to the choice of statistical hadronization model. We start by giving an overview of statistical model ambiguities, and what they tell us about freeze-out dynamics. We then use Montecarlo generated data to determine sensitivity to model choice. We fit the statistical hadronization models under consideration to RHIC data, and find that a comparison χ2 fits can shed light on some presently contentious questions.
