A. Giovannini et al., COMMON ORIGIN OF THE SHOULDER IN MULTIPLICITY DISTRIBUTIONS AND OF OSCILLATIONS IN THE FACTORIAL CUMULANTS TO FACTORIAL MOMENTS RATIO, Physics letters. Section B, 374(1-3), 1996, pp. 231-237
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.
