Аннотация: Vorticity and polarization of 𝛬 and anti-𝛬 were calculated within the UrQMD model in non-central Au+Au collisions at energies of FAIR and NICA. To determine temperature and chemical potentials of the areas from where 𝛬/𝛬¯ were emitted, the fit to statistical model of ideal hadron gas was employed. Then the thermal vorticities of the areas and polarization of both hyperons were calculated. It is found that the polarization of 𝛬/𝛬¯ increases with decreasing energy of the collisions. The stronger 𝛬¯ polarization compared to that of 𝛬 is explained by different space-time distributions and different freeze-out conditions of both hyperons.
