摘要：

Results on e+e- annihilation into hadrons at c.m. energies between 22 and 31.6 GeV are presented. The data were accumulated with the PLUTO detector at PETRA. The events are dominantly of the two-jet type. The value of the relative hadronic cross section R=3.88 ± 0.22 along with the details of the sphericity and thrust distribution rule out an open (tt̄) channel (Qt = 2 3) below 30 GeV. The inclusive muon results support the above conclusion. © 1979.
