Modeling Net-Charge Fluctuations in Heavy-Ion Collisions at the LHC- / G.O.Ambaryan, A.M.Snigirev, [a.o.] // Chinese Physics C [Electronic resource]. – 2025. – Vol. 49, No. 1. – P. 014109. – URL: https://doi.org/10.1088/1674-1137/ad8a39.

Analysis of Pb+Pb data for net-charge fluctuations at LHC energies using the HYDJET++ model is presented. The strongly intensive quantities D and Σ were used to remove the effects related to system volume fluctuations. We employed two versions of HYDJET++ for the analysis. The first one is the standard or default version, whereas the second one is a modification that takes into account explicit event-by-event conservation of the electric net-charge of produced particles. The inclusion of the canonical net-charge conservation in the model allows for better description of the experimental data obtained by the ALICE and CMS Collaborations. A comparison with calculations from other models is also presented.
