Description
We examined the particle ratios of multiple meson and baryon species at central rapidity and an impact parameter of b = 5 in Pb+Pb high-energy heavy-ion collisions. The collisions were simulated using the most recent version of the Ultra-relativistic Quantum Molecular Dynamics model (UrQMD-3.4), which, unlike its predecessors, incorporates charmed particles such as D, J/ψ, Xc, and others. These charmed particles are critical in understanding particle production and the chemical freeze-out of hadronic gas. The simulations were conducted over a range of incident kinetic beam energies (lab frame) from Elab = 100 to 1000 AGeV, with parameters set to t = 400 fm/c and 200 events. Particle ratios are key for differentiating between hadronic cascade and hydrodynamical models, including a Quark-Gluon Plasma (QGP) phase transition. This study offers valuable insights into particle production dynamics across varying collision energies, shedding light on the processes leading to chemical freeze-out and thermal equilibrium. The findings advance our understanding of the phase transition in hadronic gas within high-energy heavy-ion collision systems. The results highlight the evolution of particle ratios at central rapidity and above the saturation time as collision energy increases, providing a deeper understanding of the underlying physics in such extreme conditions.
