Multiplicity Distributions in QCD and λφ³₆-model

Original · EN

It is shown that QCD with vector gluons predicts drastically different multiplicity distributions compared to the scalar λφ³-model (in 6 dimensions). In particular, the QCD predicted minimum of cumulant moments of the distributions at ranks about 57 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 57 supports the vector nature of gluons and singular kernels in QCD and gluodynamics.
