Abstract
The shoulder structure of charged particles multiplicity distributions (MD's) in full phase space in e(+)e(-) annihilation at the Z(0) peak and the quasi-oscillatory behavior of the ratio of factorial cumulants over factorial moments, H-q, as a function of the order q, are quanti tatively reproduced within a simple parametrization of the MD in terms of a weighted super position of two Negative Binomial Distributions, associated to two- and multi-jet production, i.e., to hard gluons radi ation.
