Abstract : An attempt has been made to study the multiplicity, pseudorapidity and pseudorapidity-gap distributions of relativistic charged particles produced in 208Pb208Pb collisions at 158A GeV/c. A few remarks on the said characteristics of multiparticle production in relativistic nucleus-nucleus collisions has been made. The two-, three-, four- and five-particle correlations have been studied. The rapidity-gap distributions reveal the evidence of short-range correlation which hints towards the well-established fact that the secondary particles are produced via the process of clustering. The contribution of long-range correlation is negligible while as the short-range correlations seems to play a significant role.

Keywords : Pseudorapidity; Rapidity-Gap; Multiplicity; Correlation; Clustering.
