Abstract
This paper reports a study of ring-like and jet-like events in terms of Scaled factorial Moments (SFMs) in two-dimensional space for pions produced in 16O-AgBr interactions at 60 A GeV. The analysis reveals an intermittent type of increase in SFMs with decreasing bin width in both types of events. The analysis further shows that stronger fluctuations occur in the case of ring-like events.
