Wavelet patterns in nucleus–nucleus collisions at 158A GeV

Abstract We propose to use multidimensional wavelet analysis for pattern recognition in high multiplicity events and consider some examples. Wavelet analysis reveals clustering phenomena in multiparticle production processes. Results of event-by-event studies of some nucleus–nucleus collisions at 158 A GeV are reported. The clusterization topology is found to be different in different events. Typical patterns include jets and ring-like structures. They are demonstrated here for five high multiplicity events.
