Constraining freeze-out with yields and fluctuations

Abstract

We show that the simultaneous measurement of yields and fluctuations in heavy ion collisions is capable of falsifying and constraining the statistical hadronization model. We show how such a measurement can test for chemical non-equilibrium, and distinguish between a high temperature chemically equilibrated freeze-out from a supercooled freeze-out with an over-saturated phase space. We further explain how this measurement can be used to obtain a model-independent estimate of the effect of post-freezeout hadronic interactions.
