ИСТИНА

Production of strange hadrons is studied in heavy-ion collisions at energies of BES, FAIR and NICA within the microscopic transport models. The whole interaction area is subdivided into the smaller cells. We perform the analysis of the space-time evolution of all particles in all cells, in the T-mu_B and T-mu_S planes, and the analysis in x-t of the finally emitted strange and non-strange particles. Following the time evolution of the distributions, one sees earlier freeze-out of kaons and pions compared to, e.g., protons and Lambdas. The latter appear to be frozen out at lower temperature and larger strangeness chemical potential.
