Intermittent and multifractal behaviors of multiplicity distributions in 800 GeV p-nucleus interactions.

Abstract

We use scaled factorial moments (SFM{close_quote}s) to analyze pseudorapidity fluctuations of nonstatistical origin in {ital p}-nucleus interactions at 800 GeV. The SFM{close_quote}s are found to exhibit a power-law dependence on the pseudorapidity interval size. The anomalous dimensions {ital d}{sub {ital q}} have been calculated up to order 5. The fractional dimensions {ital D}{sub {ital q}} have been extracted from the slopes of the multifractal plots. Both the multifractal and intermittency approaches have been found to be complementary to each other. The behavior of {ital D}{sub {ital q}} and {ital d}{sub {ital q}} with order {ital q} indicates a possible self-similar random cascading mechanism for multiparticle production. {copyright} {ital 1996 The American Physical Society.}
