Kaon femtoscopy in Au+Au collisions at √S _NN = 200 GeV at the STAR experiment

摘要

In this proceedings, the STAR preliminary results on femtoscopic correlations of identical kaons from Au+Au collisions at =200 GeV are presented. The measured kaon source radii are studied as a function of collision energy as well as centrality and transverse pair mass m _(T). In addition, extracted kaon blast-wave freeze-out parameters are presented.
