Abstract
Using event-by-event fluctuations, we study the diffusion parameters of net-charge, net-pion, net-kaon, and net-proton in the heavy-ion jet interaction generator (HIJING), and ultra-relativistic quantum molecular dynamics (UrQMD) models at different collision energies \(\sqrt{s_{_{NN}}}\) available at BNL Relativistic Heavy Ion Collider (RHIC). The diffusion parameter (\({\sigma }\)) of net-charge and identified particles are estimated in rapidity space at various \(\sqrt{s_{_{NN}}}\). It is observed that, the \({\sigma }\) values are independent of collision energies but emphasises the particle-species dependence of diffusion coefficient in the QGP medium. The present work on particle-species dependence of diffusion coefficient provides a baseline for comparison with the experimental data.
