Abstract:
This work is a brief history of the almost 50 years of Relativistic Nuclear Physics with accelerator systems, taking into account the continuous presence of the members of the Faculty of Physics staff in the initiation and developing of this important field of the contemporary Nuclear Physics. Some important results, as well as, simulation results obtained by the research group from Faculty of Physics, University of Bucharest, during the time, are included. The simulations have been done using YaPT system, developed in own research center. The results reflect possible bulk properties of the high excited and dense nuclear matter formed in nucleus-nucleus collisions, as well as different behaviours of the nuclear matter from participant region and possible influences of the spectator regions on these quantities. Different hypotheses are tested, and analysis methods include global analysis.
Therefore, some experimental results from experiments performed at JINR, RHIC-BNL, LHC-CERN, as well as simulated results for CBM-FAIR and MPD-NICA-JINR are used to discuss nuclear matter behaviour, both in thermodynamic and hydrodynamic perspectives. Interesting results on compressibility and viscosity and the possible dependencies on the collision geometry and collision energy are included. Discussions on phase transitions in very dense and hot nuclear matter are included, too. A synthesis of the major results of the group during the time completes this work.
