One- and two-dimensional analysis of the factorial moments in 200 GeV/nucleon p, 16O and 32S interactions with Ag/Br nuclei

Scaled factorial moments, corrected for the shape of the single particle pseudorapidity distribution are analysed in terms of the pseudorapidity variable and in two-dimensional (pseudorapidity and azimuthal angle) space. An intermittent, power-law growth of the moments with decreasing bin size is found in both cases, with two-dimensional analysis revealing a much stronger effect for nucleus-nucleus data. Furthermore, the intermittent patterns are more evident for proton-nucleus collisions than for the nucleus-nucleus data where the heaviest nucleus examined, 32S shows the weakest effect. 15 refs., 5 figs., 3 tabs.
