Abstract

The PHENIX experiment measured Bose-Einstein quantum-statistical correlations of charged kaons in Au+Au collisions at $\sqrt{s_{\text{NN}}}$ = 200 GeV. The correlation functions are parametrized assuming that the source emitting the particles has a L\'evy shape, characterized by the L\'evy exponent $\alpha$ and the L\'evy scale $R$. By introducing the intercept parameter $\lambda$, 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 L\'evy parameters to physical processes.
