Abstract
This work presents the analysis of ring-like and jet-like events in terms of factorial correlations of 32S–Ag/Br interactions at 200 A GeV. The investigation reveals that the correlated moments increase with decreasing bin–bin separation D, following power law, which suggests the presence of an intermittent nature of self-similar dynamical fluctuation pattern for ring-like and jet-like events. The analysis further shows that the strength of the non-statistical fluctuations is larger for ring- like events than those of jet-like events i.e. correlations in bins are more pronounced in case of ring-like events. However, ring-like events are consistent with the predictions of the α-model, but jet-like events are not.
