Evidence for Gluon Bremsstrahlung in e+ e Annihilations at High Energies
Phys. Lett. 86B (1979) 418;

Abstracts
We report our results on the reactions e+e- hadrons in the energy range 13 < E cm < 31.6 GeV and compare them with q jets described in the quark-parton model and with first-order QCD predictions including gluon emission (qgjets). 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.
