TL;DR: In this article, the authors report results on the reactions e+e−− → hadrons in the energy range 13 ⩽ Ecm ⌽ 31.6 GeV and compare them with qq jets described in the quarkparton model and with first-order QCD predictions including gluon emission (qqg jets).

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.
