A `soft + hard' model for heavy-ion collisions

Abstract

We describe the spectra of neutral pions stemming from AuAu collisions at $\sqrt{s}$ = 200 AGeV in a `soft + hard' model. The model is based on the assumptions that hadrons stemming from hard processes are described via perturbative quantum chromodynamics improved parton model calculations, while those stemming from the Quark-Gluon Plasma (we refer to as soft yields) can be described in a super-statistical model induced by multiplicity fluctuations. The obtained dependence of the parameters of the model on the event centrality is compared to what is observed in PbPb collisions at $\sqrt{s}$ = 2.76 ATeV.
