TL;DR: In this article, the authors compared 2nd-order QCD calculations with 3-and 4-jet models in the energy range of 14.0-46.7 GeV and showed that the observed excess of spherical events can partially be explained by the production of multi-parton events expected from higher order QCD contributions.

TL;DR: In this paper, the average charged multiplicity has an energy dependence much stronger than ln s and similar to that reported for pp collisions, and the dispersion Dch for e+e− and pp interactions at the same center of mass energy is significantly larger than in pp collisions.
