Particle physics theoretical and experimental studies

Fluctuations in particle densities of non-statistical origin are studied in central 16O+Ag(Br) and 32S+Au interactions at 200 A GeV. Non-statistical fluctuations in the 32S-induced interactions seem to enhance the local particle densities, and suggest the presence of intermittancy. The fluctuations are found to be accompanied by a clustering tendency also in the azimuthal plane. A new method for the study of azimuthal correlations is proposed.
