Transverse Momentum and Rapidity Dependence of HBT Correlations in Au+Au Collisions at sqrt(sNN) = 62.4 and 200 GeV
Abstract
Two-particle correlations of identical charged pion pairs from Au+Au collisions at sqrt(sNN) = 62.4 and 200 GeV were measured by the PHOBOS experiment at RHIC. Data for the 15% most central events were analyzed with Bertsch-Pratt and Yano-Koonin-Podgoretskii parameterizations using pairs with rapidities of 0.4 < yππ < 1.3 and transverse momenta 0.1 < kT < 1.4 GeV/c. The Bertsch-Pratt radii Ro and Rl decrease as a function of pair transverse momentum, while Rs is consistent with a weaker dependence. Ro and Rs are independent of collision energy, while Rl shows a slight increase. The source rapidity yykp scales roughly with the pair rapidity yππ, indicating strong dynamical correlations.
