Description
The theoretical description of the femtoscopy scales in ultrarelativistic heavy-ion collisions at different energies and for different colliding ion pairs (Au + Au collisions at the top RHIC energy $\sqrt{s_{NN}}=200$ GeV, Pb + Pb collisions at the LHC energies $\sqrt{s_{NN}}=2.76$ and $\sqrt{s_{NN}}=5.02$ TeV, the LHC Xe + Xe collisions at $\sqrt{s_{NN}}=5.44$ TeV) is provided within the integrated HydroKinetic model (iHKM). The comparison of the model simulation results, obtained for the considered collision types at the similar values of the mean charged particle multiplicity ⟨$dNch/dη$⟩ shows that the magnitudes of the corresponding interferometry radii depend not only on ⟨$dNch/dη$⟩ but also on the geometric sizes of the colliding nuclei.
