Initial fluctuations and correlation of finite distributions of secondary particles in interaction of heavy ions with photoemulsion nuclei

Abstract

The study of the peculiarities of the distribution of secondary particles depending on the degree centrality and the degree of asymmetry of the interacting nuclei, is performed. The number of multicharged fragments of the projectile nucleus N f in interactions sharply asymmetric nuclei depends on the centrality degree of interaction. At that, the events with N f =1 are separated clearly in the distribution of the total charge of the fragments of a projectile nucleus Q depending on the nature of the correlation of the number of fragments of the target nucleus and the multiplicity of secondary particles.

Event-by-event fluctuations of maximum particle density with respect to the width of the pseudo-rapidity interval at a few A GeV/c

“…Hence it is very important to know the centrality of collisions. In nuclear [34][35][36][37][38][39][40][41][42]. Here Q is the total charge or sum of the charges of the non-interacting projectile fragments.…”

An outlook to centrality dependence of event-by-event fluctuations of maximum pseudo-rapidity gap

“…Centrality will gradually decrease as the value of Q increases. Several authors have investigated different aspects of central collisions using emulsion data in different works in the literature using Heckman criteria [46][47][48][49][50][51][52][53]. Now one point should be mentioned here.…”
