Description
The technique of correlation femtoscopy helps one not only to estimate the geometric dimensions and lifetime of the particle emission region in nucleus-nucleus collisions, but also help to answer the question of whether the source has a boost-invariant spatiotemporal structure. This work is aimed to studying the femtoscopic parameters of identical-pion emission region in Au+Au collisions at $\sqrt{s_{NN}} = 3$ GeV in the STAR experiment. The extracted radii ($R_{out}, R_{side}, R_{long}, R^{2}_{out-long}$) and correlation strength ($\lambda$) are presented as a function of collision centrality, pair rapidity and transverse momentum. The obtained femtoscopic parameters are compared with the model predictions.
