摘要：

We report our results on the reactions e+e- → hadrons in the energy range 13 ≤ Ecm ≤ 31.6 GeV and compare them with qq̄ jets described in the quark-parton model and with first-order QCD predictions including gluon emission (qq̄g jets). At high energies the observed features of one-sided jet broadening, sea-gull effect and planar events with a three-jet structure represent a gross violation of the parton model without gluons and find a most natural interpretation if gluon bremsstrahlung is included. © 1979.
