In particular, the QCD predicted minimum of cumulant moments of the distributions at ranks about $5\div7$ 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 $5\div7$ supports the vector nature of gluons and singular kernels in QCD and gluodynamics.6 pages, plain LaTeX, 3 figures (not included)High Energy Physics - Phenomenologytext
