Bose-Einstein correlations of charged pion pairs in Au+Au collisions at &#8730;s<SUB>NN</SUB>=200 GeV

Bose-Einstein correlations of identically charged pion pairs were measured by the PHENIX experiment at midrapidity in Au+Au collisions at &#8730;sNN=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&lt;&lt;kT&gt;&lt;1.2 GeV/c. The centrality dependence of all radii is well described by a linear scaling in Npart1/3, and Rout/Rside for &lt;kT&gt;~0.45 GeV/c is approximately constant at unity as a function of centrality
