Description

Multiplicity distributions in e+e- and proton-proton collisions analyzed via the combinants method exhibit oscillatory behavior of the modified combinants. The possible sources of these oscillations and their impact on our understanding of the multiparticle production mechanism were discussed [1-5]. The set of combinants, Cj provides a similar measure of fluctuations as the set of cumulant factorial moments, Kq, which are very sensitive to the details of the multiplicity distribution and were frequently used in phenomenological data analyses. However, while cumulants are best suited to studying the densely populated region of phase space, combinants are better suited for studying sparsely populated regions because the calculation of Cj requires only a finite number of probabilities P(N
