2-PARTICLE AND MANY-PARTICLE CORRELATIONS IN NUCLEAR AND HIGH-ENERGY PHYSICS

The relevance of the scale-invariance and intermittency ideas for both the multiparticle production process and the nuclear multifragmentation process is discussed. The studies of the multiparticle distributions using the correlation functions, the scaled factorial moments and the correlation integral are described. Several theoretical models of high energy multiparticle collisions and multifragmentation having the scale-invariance properties, are presented and possible theoretical ideas leading to the scaling features in these processes are explained. We present also a short resume of the experimental status in this domain of research.
