Lévy femtoscopy with PHENIX at RHIC

PHENIX Collaboration

Research output: Contribution to journalArticle


In this paper we present the measurement of charged pion two-particle correlation functions and their Lévy parameters in 0-30% centrality √sNN = 200 GeV Au+Au collisions. The measured correlation functions can be statistically well described by Bose-Einstein correlation functions from Lévy-shaped source distributions. Using a fine transverse momentum binning, we extract correlation strength parameter λ, Lévy index α and Lévy scale parameter R as a function of pair transverse mass mT , in 31 bins from 228 to 871 MeV, separately for positive and negative pion pairs. We discuss the physical interpretation of the mT -dependence of the parameters.
