Lévy femtoscopy with PHENIX at RHIC
arXiv:1711.05575 · doi:10.3390/universe3040085
Abstract
In this paper we present the measurement of charged pion two-particle femtoscopic correlation functions in 200 GeV Au+Au collisions, in 31 average transverse mass bins, separately for positive and negative pion pairs. Lévy-shaped source distributions yield a statistically acceptable description of the measured correlation functions, with three physical parameters: correlation strength parameter lambda, Lévy index alpha and Lévy scale parameter R. The transverse mass dependence of these Lévy parameters is then investigated and their physical interpretation is also discussed, and the appearance of a new scaling variable is observed.
