Multiplicity Distributions in QCD and $\lambda {\phi }_6^3$-model

Abstract

It is shown that QCD with vector gluons predicts drastically different multiplicity distributions compared to the scalar $\lambda {\phi }^3$-model (in 6 dimensions). In particular, the QCD predicted minimum of cumulant moments of the distributions at ranks about $5÷7$ does not reveal itself in the scalar model. The oscillations at higher ranks survive only. Thus, the experimental fact of that minimum at ranks about $5÷7$ supports the vector nature of gluons and singular kernels in QCD and gluodynamics.
