Abstract

The method of correlation femtoscopy makes it possible to estimate the parameters of the particle-emitting region (radius of emission region, \(R\), and correlation strength, \(\lambda\)). Measurement of femtoscopic radius dependence on transverse momentum of particle pairs, \(k_{T}\), is an important tool for studying the dynamics of the emission process. This work is devoted to the study of momentum correlations of identical pions produced in Au \(+\) Au collisions at \(\sqrt{s_{NN}}=3\) GeV using the UrQMD (Ultrarelativistic Quantum Molecular Dynamics) model. Three-dimensional femtoscopic analysis was performed as a function of \(k_{T}\), rapidity and collision centrality. Physical implications will be discussed.
