Sensitivity of Multiplicity Fluctuations to Rapidity in High-Energy Nucleus-Nucleus Interactions

The multiplicity fluctuations in the relativistic charged particles produced in 28Si-nucleus interactions at two different energies are investigated in terms of a scaled variance. The main binning condition used in the present study is to expand the range of pseudorapidity along both sides of a central rapidity which is obtained from the rapidity distribution of each interaction considered. The dependence of the multiplicity fluctuations on the projectile energy and target size is investigated, and the results are compared with those obtained from the FRITIOF model.
