摘要：
Possible breaking of CP-invariance of the strong interactions is one of the actual problems in quantum chromodynamics. The preliminary estimations of correlators within the framework of the chiral magnetic effect are presented for different beam types and collision energies. These correlators characterized the asymmetry of the emission of charged particles with respect to the reaction plane in non-central nucleus-nucleus collisions are calculated for two various nuclear densities, namely, for approach of hard sphere and for two-component Fermi model.
