Particle Ratios in a Multicomponent Nonideal Hadron Resonance Gas

We have considered formation of a multicomponent nonideal hot and dense gas hadronic resonances in the ultrarelativistic heavy ion collisions. In statistical thermal model approach, equation state (EoS) noninteracting ideal hadron resonance (IHRG) does not incorporate either attractive part or short-range repulsive baryonic interaction. On other hand, (NIHRG) model, we can these interactions using van der Waals (VDW) type approach. Studies been made to see its effect on critical parameters quark-hadron phase transition. However, it also lead modifications calculated relative particle yields. this paper, attempted understand such Waals-type yields studied their dependences system’s parameters, as temperature baryon chemical potential μ B . taken into account decay contributions heavier resonances. These results ratios are compared with corresponding obtained from point-like, i.e., IHRG model. It is found that get modified by incorporating interactions, especially baryon-rich system which expected be formed at lower RHIC energies, SPS forthcoming CBM experiments due high degree nuclear stopping experiments.
