Moments of multiplicity distributions in higher-order perturbation theory in QCD
Dremin I. M. , Nechitailo V. A.
The ratio of the cumulant moments of the multiplicity distributions of partons to the factorial moments exhibits some qualitatively distinct features (minima and maxima) when higher-order terms of the expansion of perturbative QCD are incorporated in the nonlinear equation for the generating function. The correspondence between these results and experimental data is discussed.
