Wavelet patterns in nucleus-nucleus collisions at 158A GeV

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