Abstract

Femtoscopy is one of the methods to learn about properties of strongly interacting nuclear matter. Using it, information about space-time characteristics of the particle-emitting source can be obtained. The radii of source can be extracted from the analysis of the correlation functions of particles pairs with low relative momenta. High statistics data sets from RHIC have made it possible to study the strange particle correlations. The lightest strange particles are charged and neutral kaons. Kaons provide a cleaner probe of the particle-emitting region as compared to pions because they are less affected by resonance decays and have smaller cross section with hadronic matter. Thanks to these properties, kaon correlation functions can be sensitive to the early stage of the collisions evolution and also provide different information about particle-emitting source. In this report, one-dimensional correlation functions of charged and neutral kaon systems produced in Au+Au collisions at Beam Energy Scan energies measured by the STAR experiment at RHIC will be presented.
