Abstract

EIBose-Einstein correlations of identically charged pion pairs were measured by the PHENIX experiment at midrapidity in Au + Au collisions at $\sqrt S_{NN}$=200 GeV. The Bertsch-Pratt radius parameters were determined as a function of the transverse momentum of the pair and as a function of the centrality of the collision. Using the standard core-halo partial Coulomb fits, and a new parametrization which constrains the Coulomb fraction as determined from the unlike-sign pion correlation, the ratio Rout/Rside is within 0.8–1.1 for 0.25$<$kT$<$1.2 GeV/c. The centrality dependence of all radii is well described by a linear scaling in N, and Rout/Rside for kT$\sim$0.45 GeV/c is approximately constant at unity as a function of centrality
