The ratio of cumulant to factorial moments of experimental multiplicity
distributions has been calculated for e+e− and hh interactions in a
wide range of energies. As a function of the rank it exhibits an initial steep
decrease and a series of oscillations around zero. Those features cannot be
reproduced by the Negative Binomial Distribution. A comparable behaviour is
instead predicted in high-energy perturbative QCD. The presence of a
qualitatively similar behaviour for different processes and in wide energy
intervals suggests speaking of an approximate scaling of the cumulant to
factorial moment ratio.Comment: Submitted to Phys.Lett.B; Latex document, 11 pages, 4 PostScript
