摘要
In very high energy collisions, many particles are produced and distributed in the available phase space volume in various ways. With new accelerator facilities (especially, for nucleus-nucleus collisions), the problem of pattern recognition in high multiplicity events becomes crucial in order to classify such events and to separate those with some special features (e.g. ring-like events, jets and other regular patterns). This letter presents the first attempt to use wavelet technique for pattern recognition in nucleus-nucleus collisions. After describing the method in general, we demonstrate its usefulness by applying it to a single event of Pb-Pb collision at 158A GeV with 1072 charged particles produced and discuss results obtained for some other events. Further extension of the method is proposed.
