Dynamics of the Relativistic Heavy Ion Collisions

  • J. Cugnon
Part of the NATO ASI Series book series (NSSB, volume 130)

Abstract

The boundaries of the relativistic heavy ion collision domain are loosely defined. Obviously, the lower limit is certainly at an incident beam energy (per nucleon) larger than the highest energy discussed by Prof. M. Lefort in his lectures,2 about 44 MeV/A. The upper limit separating relativistic and ultrarelativistic collisions (discussed elsewhere by Prof. G. Baym3) is even more diffuse. As a convenient but perhaps not very meaningful guide, we will use the present operating accelerators. The Bevalac has accelerated for now twelve years ions up to Ar from 250 MeV/A to 2.1 GeV/A (which corresponds to a Lorentz factor in the lab frame from γinc = 1.26 to 3.23).Very recently Nb and La beams have been accelerated and Au and U beams are going to be exploited in the very near future. The Synchrophasotron at Dubna has the more energetic ions available nowadays: up to 4 GeV/A, but unfortunately, only light ions (up to 12C) are available. In the last months or so, C and O beams have been accelerated in the Saturn machine in Saclay at an energy around 1 GeV/A. The Ganil machine in France and the MSU machine should cover the range between 100 MeV and 400 MeV per nucleon, but they are just starting now. As most of the now available data have been obtained in Berkeley, our purpose here is to discuss the physics in the Bevalac range, with some excursions in the Ganil regime.
