[en] This paper is based on three lectures presented at the Prague Seminar on Relativistic Heavy-Ion Physics in September 1994. The first lecture, following a general introduction, focuses on three different aspects of the CERN experiment WA80. The author first presents results on global event characteristics deduced primarily from measured distributions of transverse energy and of forward energy. The purpose is to introduce the main general features of nucleus-nucleus reactions at the highest energies currently available. He highlights the role of projectile-target geometry, discusses the degree of nuclear stopping, and estimates the energy densities attained in these reactions. This discussion is followed by a presentation of one of two topics that are unique to the WA80 experiment and which are not addressed by any of the other CERN collaborations that study nucleus-nucleus reactions: direct measurements of photons. The second topic unique to WA80, measurements of proton-proton correlations in the target-fragmentation region, is covered in the first part of the second lecture. The remainder of the second lecture is devoted to a selective overview of results obtained at the AGS accelerator of Brookhaven National Laboratory (BNL). The third lecture is devoted to a discussion of the two main experiments, STAR and PHENIX, planned for the Relativistic Heavy Ion Collider, RHIC, under construction at BNL

[en] The closed-form theoretical model, already employed to successfully describe in a single picture, the nonequilibrium component and the evaporation component of the angular correlation between particles and reaction residues emitted in a peripheral heavy-ion collision, is here revisited. This revised approach, applied to the C-α differential multiplicities for the "1"6O + "5"8Ni at 6 MeV/A and "1"6O + "4"8Ti at 8.3 MeV/A deep inelastic collisions, allows to explain more in detail the reaction mechanism of such processes.

[en] ALICE is a dedicated Heavy-Ion experiment proposed for the future LHC collider at CERN. The main goals of the ALICE Inner Tracking System are the reconstruction of secondary vertexes and the tracking and identification of low-p_t electrons; at the same time, it will provide a significant improvement of the momentum resolution at large p_t and the tracking and identification of low-p_t hadrons. The ITS will consist of five cilindrical layers of radii from 7.5 to 50 cm. of high-resolution detectors. The unprecedented particle density foreseen, of up to 8000 particles per unit η, imposes the use of sophisticated, and often innovative, technologies for the detectors, the electronics and the support and cooling system. Therefore, extensive R ampersand D programs are now being pursued on various aspects of the project. Here are presented the basic ideas for the design, a few examples of the expected performance, and a brief overview of the ongoing R ampersand D

[en] An effective method for calculating the potential energy of a dinuclear system is proposed. Analytic expressions for calculating the nuclear part of the nucleus-nucleus potential in the double-folding form are obtained. A relationship between this potential and the proximity potential is found. Effects of deformation and mutual orientation of nuclei on the interaction potential are studied. It follows from a comparison of calculated potential energies with nuclear binding energies that excited states of some nuclei can be treated as dinuclear or trinuclear systems. 27 refs., 7 figs

[en] The conditions necessary for the formation of a superfluid component in an expanding system of excited matter created in nuclear collisions are investigated. For a realistic resonance gas equation of state, it is found that the decoupling from local chemical equilibrium must occur at high temperatures and baryon number densities for a sizable amount of condensate to be formed

[en] Source size parameters measured via two-particle interferometry in experiment NA44 for 200 GeV/nucleon S+Pb collisions are compared to calculations using the RQMD event generator. Reasonable agreement is found in most cases. The event generator is then used to compare the open-quotes trueclose quotes size of the particle-emitting source to the measured size parameters and to discuss the difficulties in defining the open-quotes trueclose quotes source size
