CUMULANT TO FACTORIAL MOMENT RATIO AND MULTIPLICITY DATA

The ratio of cumulant to factorial moments of experimental multiplicit y distributions has been calculated for e(+)e(-) and hh interactions i n a wide range of energies. As a function of the rank it exhibits an i nitial 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 approxi mate scaling of the cumulant to factorial moment ratio.
