It provides new femtoscopic correlation measurements for various particles in heavy-ion collisions at different energies and centralities.

Findings

Source size depends on collision energy and centrality

Correlation functions reveal details of final state interactions

Implications for light nuclei production mechanisms

Abstract

In these proceedings, we present the measurements of proton, light nuclei, and strange particle with neutral kaons correlation functions in Au+Au collisions at the BES program and top RHIC energy. The experimental results will be compared with model calculations to extract the size of emitting source and the properties of final state interactions. The collision energy and centrality dependence of the source size will be studied. Further, the implications for the production mechanism of light nuclei will be discussed.
