Abstract

A study of the energy behavior of the interferometry radii is carried out for the RHIC and LHC energies within the hydrokinetic model (HKM). The hydrokinetic predictions for the HBT radii at LHC energies are compared with the recent results of the ALICE Collaboration. The role of non-equilibrium and non-hydrodynamic stage of the matter evolution in formation of the femtoscopy scales at the LHC energies is analyzed. For this aim we develop the hybrid hydrokinetic model.
