Entropy and fractal characteristics of multiparticle production at relativistic heavy ion interactions.

Abstract

We present the analysis of multiplicity distributions of charged secondary particles produced in minimum bias and central interactions of $^{32}\mathrm{S}$ and $^{16}\mathrm{O}$ at 200A GeV, $^{16}\mathrm{O}$ at 60A GeV, $^{28}\mathrm{Si}$ at 14.5A GeV, and protons at 800 GeV with nuclear emulsion in terms of the information entropy and higher generalized fractal dimensions. Comparisons of the $^{28}\mathrm{Si}$ data with Monte Carlo model venus and $^{32}\mathrm{S}$ data with fritiof model are also presented.
