Abstract:
Nucleus-nucleus collisions at the Synchrophasotron and the Nuclotron from the JINR Dubna can lead, in the overlapping region of the two colliding nuclei, to a hot and dense nuclear matter. In this region, new states of the nuclear matter can appear. Many attempts consider that in this energy region a transition to a new state containing a few quarks can appear. Therefore, in the present work we reconsider some previous experimental results obtained in nucleus-nucleus collisions at the Synchrophasotron and Nuclotron energies in this perspective. Also, new experimental results obtained in C-Cu collisions at the Nuclotron energies using MARUSYA experimental set-up are included.
The behaviour of the particle yields, multiplicities and associated distributions, as well as the behaviour of the antiparticle to particle ratios will be presented.
For the new experimental results obtained in MARUSYA Experiment, the time-of-flight (TOF) particle identification method is used. Interesting experimental results are obtained and new aspects related to different regions of the nuclear matter phase transitions diagram are presented.
