Erratic Multiplicity Fluctuation in Heavy-Ion Collisions at High Energy

Abstract

The results reported in this manuscript are an attempt to look for the occurrence of erratic multiplicity fluctuations in pseudorapidity space of the secondary particles produced in 16 O-nucleus interactions at an incident momentum of 3.7A GeV/c and to compare our results with the finding of other researches on dynamical fluctuations at various projectile energies. The analysis heavily relies on the method of normalized factorial moments and the binning of the phase space. In this analysis we have obtained results on the normalized factorial moments and other physical parameters derived from them. Results obtained for the experimental data are compared with the results for FRITIOF simulated events. The results on F 2distribution, C pq -moments and on Σ q obtained in the present study hints towards the existence of chaoticity in the multiparticle production in high energy nucleus-nucleus collisions. Occurrence of such non-statistical fluctuations further suggests the presence of correlated particle production in relativistic nuclear collisions.
