Аннотация:Charged-particle correlations in terms of charge balance functions (CBF) are studied within HYDJET++ model for nucleus–nucleus interactions at the energies of the Beam Energy Scan (BES) program at RHIC and NICA collider. It is shown that taking into account event-by-event conservation of the electric net-charge of produced particles together with finite values of isospin, strangeness, and baryon chemical potentials in the model, allows one to reproduce STAR/RHIC data on CBF pseudorapidity widths in Au + Au collisions at center-of-mass energy per nucleon pair √sNN = 7.7 and 11.5 GeV. Based on the model results at RHIC energies, a prediction for CBF pseudorapidity widths for Bi + Bi collisions at planned NICA energy of √sNN = 9.2 GeV is made.
