Abstract

Present study is an attempt to have a detailed look into event-by-event(e-by-e) pseudorapidity fluctuations of the relativistic charged particles produced in $^{28}$Si-nucleus interactions at incident momenta 4.5A and 14.5A GeV/c.The method used in the present study makes use of a kinematic variable which is derived in terms of the average pseudo-rapidity and the total number of particles produced in a single event. The multiplicity and pseudorapidity dependence of these fluctuations have also been studied. The results obtained for the experimental data are compared with HIJING simulation.
