Cumulant to factorial moment ratio and multiplicity data
Abstract
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.
