Transverse-Mass Dependence of Two-Pion Correlations in Au+Au Collisions at (sNN) = 130 GeV
Abstract
Two-pion correlations in (sNN) = 130 GeV Au+Au collisions at RHIC have been measured over a broad range of pair transverse momentum kT by the PHENIX experiment at RHIC. The kT dependent transverse radii are similar to results from heavy-ion collisions at (sNN) = 4.1, 4.9, and 17.3 GeV, whereas the longitudinal radius increases monotonically with beam energy. The ratio of the outwards to sidewards transverse radii (Rout/Rside) is consistent with unity and independent of kT.
