Phys. Rev. Lett. 62, 1713–1716 (1989)Experimental evidence for the non-Abelian nature of QCD from a study of multijet events produced in e+e- annihilationReceived 29 December 1988; published in the issue dated 10 April 1989 We present evidence for the non-Abelian nature of QCD from a study of multijet events produced in e+e- annihilations from √s =50 to 57 GeV in the AMY detector at the KEK storage ring TRISTAN. A comparison of the three-jet event fraction at TRISTAN to the fraction of the DESY storage ring PETRA shows that the QCD coupling strength αs decreases with increasing Q2. In addition, measurements of the angular distributions of four-jet events show evidence for the triple-gluon vertex. © 1989 The American Physical Society URL:
