Abstract
Femtoscopy of two non-identical particles in heavy ion collisions enables one to study the space-time asymmetry in the particle's emission process. Theoretical studies based on EPOS model performed for collision energies from the Beam Energy Scan program in STAR allow us to investigate the dependence of source sizes and dynamics effects. Obtained information will enable us to predict the collective behaviour of femtoscopic particle's source.
Highlights
The two-particles emission source size can be extracted using the femtoscopy method
First the source parametrization has to be assumed e.g. the source density should be considered as a gaussian[6], to fit the correlation function the CorFit [7] tool is use
In order to determine the source sizes the gaussian source distribution are assumed, using such parametrization the source size are deduced for four different two-particles systems for Minimum Bias data
Summary
The two-particles emission source size can be extracted using the femtoscopy method.
