Description

Two-particle Bose-Einstein quantum-statistical correlations of charged
kaons were measured at $\sqrt{s_{NN}}=200$ GeV collision energy by the
PHENIX experiment. Encouraged by previous results, a Levy-shaped particle
emitting source was assumed and the parametrizations of the measured
correlation functions were performed accordingly. The shape of these
functions is characterized by the Levy exponent $\alpha$ while the width
of the distribution is described by Levy scale $R$. Taking into account
for the core-halo picture of the source, the $\lambda$ intercept
parameter can be introduced. These three parameters and their
combinations were investigated as the function of transverse mass and
the results were compared to previous measurements of pion-pion
correlations measured by the PHENIX experiment. The comparison could
shed light on the origin of the Levy distribution in two-particle
correlations and the possibly physical interpretation of its parameters.
