Title: Pion Interferometry at RHIC: Probing a Thermalized Quark-Gluon Plasma?

Abstract

We calculate the Gaussian radius parameters of the pion-emitting source in high-energy heavy-ion collisions, assuming a first-order phase transition from a thermalized quark-gluon plasma (QGP) to a gas of hadrons. Such a model leads to a very long-lived dissipative hadronic rescattering phase which dominates the properties of the two-pion correlation functions. The radii are found to depend only weakly on the thermalization time {tau}{sub i} , the critical temperature T{sub c} (and thus the latent heat), and the specific entropy of the QGP. The model calculations suggest a rapid increase of R{sub out}/R{sub side} as a function of K{sub T} if a thermalized QGP were formed.
