摘      要：This study presents the investigations on the occurrence of multiplicity correlations in the particle multiplicities in forward and backward hemisphere in the multiparticle states produced in 2 8 Si nuclei with various targets at two different energies. The forward-forward and forward-backward dispersions are looked into. The variation of the correlation strength as a function of the pseudorapidity range is investigated and its dependence on target mass as well as the incident energy is studied. In order to estimate the contribution of non-statistical fluctuations, we use the deviation of the value of effective cluster multiplicity from unity as the benchmark.
