Abstract

This paper presents a study of bin–bin correlation of the produced shower particles in the pseudo-rapidity space by the method of factorial correlator in $^{16}$ $^{16}$ O-AgBr and $^{32}$ $^{32}$ S-AgBr interactions at 4.5 $A$ $A$ GeV/ $c$ $c$ . The correlated moments are found to increase with decreasing bin–bin separation D, following a power law. Strong bin–bin correlation is exhibited by the experimental data. Experimental data also supports the validity of log normal approximation. Experimental analysis has been compared with the results obtained from the analysis of events simulated by UrQMD model.
