Experimental evidence for the non-Abelian nature of QCD from a study of multijet events produced in e+e- annihilation
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 ±s 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.
