We study the fluctuations of net charge, net pion, net kaon, and net proton using the νdyn variable in the heavy-ion jet interaction generator (HIJING), ultrarelativistic quantum molecular dynamics (UrQMD), and hadron resonance gas (HRG) model at different collision energies sNN. It has been observed that the values of νdyn strongly depend on Δη in the HIJING and UrQMD models and are independent in the HRG model. The present work emphasizes the particle species dependence of net charge fluctuation strength and provides a baseline for comparison with the experimental data.
