Abstract:
Current heavy ion Physics researches for relativistic nuclear collisions have, as first objectives, the study of nuclear matter phase diagram and the finding of the critical point for every phase transition type in nuclear matter.
Relativistic nuclear Physics group of “The Research Center of Nuclear Matter in Extreme Conditions” from Faculty of Physics, Bucharest, has been involved, as an institution, in the CBM (Compressed Baryonic Matter) experiment from FAIR-GSI Darmstadt, Germany, since 2008. This fact offers the opportunity for important studies of nuclear matter at lower temperatures, compared to other experiments (RHIC experiments and ALICE-LHC experiment), but with higher nuclear densities.
This work presents the results obtained with the aid of UrQMD and AMPT generators, for Au+Au relativistic nuclear collisions at FAIR-GSI (Facility for Antiproton and Ion Research) specific energies, using CBM detectors. The estimations of hadrons ratios (pion,kaon,proton) - as a function of the transverse and total momentum, as well as rapidity - and their multiplicities are of great importance for the phase transitions in nuclear matter, including the start condition for quark-gluon plasma formation.
