Forward-backward multiplicity fluctuations in relativistic heavy-ion collisions

Studies involving multiparticle correlations are regarded as an important tool to explore the mechanism of particle production in hadronic and heavy ion collisions. Both short-range and long-range correlations have been observed in the past decades which have been interpreted via the concept of clustering, i.e clusters are formed in the initial stage of the interaction which finally decay isotropically in their center of mass frame to real hadrons. An attempt is, therefore, made to investigate the forward-backward correlation in AA collisions by analyzing the experimental data involving the interactions of 32S and 16O with AgBr nuclei in emulsion at 200 A GeV/c
