Description

We have observed 16 events of the type μ+μ- + (missing energy and momentum) from e+e- annihilations at center-of-mass energies between 6.4 and 7.4 GeV. Taking into account QED backgrounds, we find an excess of 11 anomalous dimuon events. If these are attributed to the production and subsequent decay of a pair of heavy leptons L+-, we obtain the muonic braching ratio B ((L+ → μ+ν/sub μ/nu-bar/sub L/)/ (L+ → all)) = 0.22/sup +0.07//sub -0.08/
