Centrality dependence of bulk fireball properties in sNN=200GeV Au-Au collisions

We explore the centrality dependence of the properties of the dense hadronic matter created in sNN=200 GeV Au-Au collisions at the Relativistic Heavy Ion Collider. Using the statistical hadronization model, we fit particle yields known for 11 centrality bins. We present the resulting model parameters, rapidity yields of physical quantities, and the physical properties of bulk matter at hadronization as function of centrality. We discuss the production of strangeness and entropy.
