Abstract
The particle ratios k+ /π +, π− /K −, p̄/π− , Λ/π − , Ω/π− , p/π+ , π − /π+ , K −/K +, p̄/p, Λ̄/Λ, Σ̄/Σ, Ω̄/Ω measured at AGS, SPS and RHIC energies are compared with large statistical ensembles of 100,000 events deduced from the CRMC EPOS 1.99 and the Ultra-relativistic Quantum Molecular Dynamics (UrQMD) hybrid model. In the UrQMD hybrid model two types of phase transitions are taken into account. All these data are then confronted with the ideal Hadron Resonance Gas Model. The two types of phase transitions are apparently indistinguishable. Apart from k+ /π+ , k− /π − , Ω/π − , p̄/π + and Ω̄/Ω, the UrQMD hybrid model agrees well with the CRMC EPOS 1.99. We also conclude that the CRMC EPOS 1.99 seems to largely underestimate k+ /π +, k − /π−, Ω/π − and p̄/π+
