Abstract
The model analysis of hadron charge correlations in heavy ion collisions was performed for energies available at NICA collider. The balance functions are considered as characteristics of such charge correlations. They represent the probability densities for oppositely charged particles to fall within a certain rapidity and azimuthal angle intervals. It has been shown that observed at STAR experiment at RHIC collider dependences of rapidity widths on centrality of gold-gold collisions at center-of-mass energies √SNN = 7.7 and 11.5 GeV per nucleon pair are reproduced by HYDJET++ model in the case of taking into account event-by-event conservation of electric charge for direct hadrons and finite values of isospin, strange and baryon chemical potentials.
