Montréal Joint High Energy Physics SeminarResonances and statistical hadronization phenomenologyGiorgio TorrieriUniversity of ArizonaSince its development by Fermi, the statistical hadronization model has been used to describe particle production of strongly interacting systems. In particular, it has been extensively used to model both abundancies and spectra of particles produced in heavy ion collisions.In this talk I will give an overview of several currently used statistical hadronization scenarios. I will then seek to differentiate them through an analysis of the yields of short-lived resonances, concentrating in particular on Λ(1520), K0(892), and Σ(1385). I will show how a combined analysis of at least two resonances can be used to understand the chemical freeze-out temperature, and the significance of post-chemical freeze-out interactions.
