Among them are, e.g., those correlations which lead to ring-like and elliptic flow shapes of individual high-multiplicity events in the polar+azimuthal angles plane. The wavelet method of analysis which allows to disentangle various patterns is proposed and applied to central Pb-Pb collisions at 158A GeV.12 pages, 5 figsHigh Energy Physics - Phenomenologytext
