Factorial Correlators and Oscillatory Multiplicity Moments at the CERN SPS Energy for Ring-Like and Jet-Like Events

We present an analysis of ring-like and jet-like events in terms of factorial correlations and oscillatory multiplicity moments of ³²S–Ag/Br interactions at 200 A GeV. The investigation reveals that the correlated moments increase with decrease in bin−bin separation D, following the power law, which suggests the presence of an intermittent nature of self−similar dynamical fluctuations pattern for ring-like and jet-like events. The analysis further shows that the strength of the non-statistical fluctuations is larger for jet-like events than those of ring-like events and total events. However, ring-like and jet-like events are not to be consistent with the total events of the α model of intermittency. To go beyond the lower order correlation, the oscillatory multiplicity moments are used to study the higher order correlation. The ratios H_q (cumulant over factorial moments, K_q/F_q) are determined for ring-like, jet-like and the total events. The presence of few-particle short range correlation is established. It is extremely interesting to observe that the oscillations of ring-like events are different from the jet-like events and the total events. However, in almost all the cases, the simulated interactions fail to replicate the experimental results.
