A comparison of statistical hadronization models

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 Monte Carlo 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.
