Centrality dependence of pseudo-rapidity distribution in nucleus–nucleus collisions at (4.1–4.5) AGeV/c

Abstract

A detailed study of the centrality dependence of pseudo-rapidity distribution has been carried out for [Formula: see text]O-emulsion interactions at 4.5[Formula: see text]AGeV/c and [Formula: see text]Ne-emulsion interactions at 4.1[Formula: see text]AGeV/c using nuclear emulsion track detector. Depending on the values of the total charges or sum of the charges of noninteracting projectile fragments, event samples were classified into four centrality classes. Maximum pseudo-rapidity density, average pseudo-rapidity values, moments of pseudo-rapidity distribution along with skewness and kurtosis of the distributions have been investigated for different centrality classes.
