摘要：
The PHENIX experiment measured two-particle Bose-Einstein quantum-statistical correlations of charged kaons in Au+Au collisions at vs(NN) = 200 GeV. The correlation functions are parametrized assuming that the source emitting the particles has a Levy shape, characterized by the Levy exponent a and the Levy scale R. By introducing the intercept parameter ?, we account for the core-halo fraction. The parameters are investigated as a function of transverse mass. The comparison of the parameters measured for kaon-kaon with those measured from pion-pion correlation may clarify the connection of Levy parameters to physical processes.
