Abstract:
The phase diagram of the nuclear matter is, today, incomplete covered by the experimental results. For filling of the missing information in different regions of this diagram new experiments have been proposed. Some of its used existing experimental facilities, at new energies, and others involve the construction of some new facilities. One of these proposed new facilities is the Facility for Antiproton and Ion Research (FAIR). This facility is built at GSI Darmstadt, Germany. Romania is founder member of the consortium that built and use this facility. One of the experiments that will work at this facility is the Compressed Baryonic Matter (CBM) Experiment. One of it tasks is to cover the missing information for nucleus-nucleus collisions at energies among SPS CERN energies and RHIC BNL energies. In this work we, as members of the CBM Collaboration‚ try to do some predictions on the thermodynamic parameters and behaviour of the detectors used in this experiment. For obtaining this information we use collision geometry and its connections with the collision dynamics, as well as some simulation codes, FLUKA code, mainly. Interesting results, in this effort to a better knowledge of the phase diagram of the nuclear matter, are obtained. Our results are in agreement with other predictions.
