Abstract:

For finding additional information on the behaviour of the nuclear matter in extreme conditions a new experiment has been proposed at the Facility for Antiproton and Ion Research (FAIR), in building at GSI Darmstadt (Germany), by a consortium of countries from entire world, namely: CBM (Compressed Baryonic Matter). The members of the research center "Nuclear Matter in Extreme Conditions" from the Atomic and Nuclear Physics Chair, Faculty of Physics, University of Bucharest, are members of this collaboration. In the two years the main research efforts have been done in a few directions, namely: - the study of the evaluation of the effects of the interactions of the primary beam and produced particle with sensitive volumes of the detectors, radiation fluxes distributions, as well as, irradiation levels in the experiment cave - simulations with different codes and estimation of different interesting physical quantities in the study of the phase transitions in nuclear matter. The results obtained during the last period are included in this work. They are connected with previous results obtained by the members of the group in other international collaboration (SHM 200 Collaboration and MARUSYA Collaboration - JINR Dubna, BRAHMS Collaboration - RHIC (Relativistic Heavy Ion Collider) at Brookhaven National Laboratory etc) The estimated results for a few interesting physical quantities are discussed for the whole available energy range, taking into account the energy range at FAIR (5-40 A GeV). Some holes in the phase diagram of the nuclear matter can be covered by the CBM Experiment and new insights could be obtained in the future.
