Particle multiplicities and fluctuations in 200 GeV Au-Au collisions

Abstract

We use the statistical hadronization model (SHM) to describe hadron multiplicity yields and fluctuations. We consider 200 GeV Au-Au collisions, and show that both event averaged yields of stable particles and resonances, and event-by-event fluctuation of the $K/\pi$ ratio can be described within the SHM using the same set of thermal parameters, provided that the phase space occupancy parameter value is significantly above chemical equilibrium, and the freeze-out temperature is $\sim 140$ MeV. We present predictions that allow to test the consistency of our results.
