A test of QCD based on 3-jet events from Z^0 decays - Adeva, B.; Adriani, O.; Aguilar-Benitez, M.; Akbari, H.; Alcaraz, J.; Aloisio, A.; Alverson, G.; Alviggi, M.G.; L3 Collaboration; Arefiev, A.; Bay, A.; Biland, A.; et al. (Elsevier)
We present a study of 43 000 3-jet events from Z^0 boson decays. Both the measured jet energy distributions and the event orientation are reproduced by second order QCD. An alternative model with scalar gluons fails to describe the data.
