Abstract
Femtoscopic measurements allow one to study the geometric characteristics of the homogeneity region created during the heavy-ion collisions. The lightest strange hadrons are charged and neutral kaons, which enhancement of the productions is one of the Quark-Gluon Plasma signatures. Analyzing high statistic data taken by the STAR experiment, it is possible to study the shortlived neutral kaons identified through their decay products: positive and negative pions. Thanks to the K0S K± analysis, one can also study the production of a0 resonance, which might be a tetraquark. These proceedings will present the femtoscopic analysis of charged and neutral kaons correlations in Au+Au collisions at √sNN = 39 GeV and 200 GeV measured by the STAR experiment.
