Abstract:
In high-energy nuclear collisions, the nuclear matter is studied at extremely high temperature and density. These conditions have the purpose of observing a new state of matter, from the phase transition of the normal hadronic matter to a deconfined phase of quarks and gluons, named quark-gluon plasma. The study of the nuclear matter phase diagram can be made using Quantum Chromodynamics (QCD). In these collisions, a large number of strongly interacting particles are produced. This system can be studied using a statistical thermal model. In this work, I will present an analysis of particle (antiparticle) ratios produced at midrapidity in relativistic nuclear collisions which are obtained by using two simulation codes, UrQMD and AMPT, from a large domain of energy. Chemical freeze-out thermodynamics parameters can be studied using particle (antiparticle) ratios as a function of center of mass energy. In addition, the study will show the energy and centrality dependence of baryon-chemical potential.
