A study of multiplicity scaling in nucleus-nucleus collisions

Abstract

Validity of Koba-Nielsen-Olesen (KNO) and generalized KNO (KNO-G) scalings is examined in ns and nc distributions by studying the behaviours of ψ(z) and Sn(z) versus z plots. A distinct departure from the KNO predictions is observed in the present study involving 4.5 and 14.5AGeV/c28Si-nucleus collisions. However, KNO-Gpredictions are found to be essentially consistent with the results obtained for different projectiles in both ns and nc distributions. All the data points are observed to approximately lie on a single curve and distortions are only observed around the tails of the multiplicity distributions.
