Title: Anomalous Lepton Production in e+e- Annihilation and New Particles
Abstract: Anomalous lepton phenomena observed in e+e- annihilation are consistently explained under the coexistence of charmed mesons and the heavy lepton. It is found that the charmed mesons are produced mainly through ψ-series resonances, making a considerable contribution to the inclusive anomalous lepton events in those rather limited resonance regions, but not giving any appreciable effect on the so-called eµ anomalous events at 4.03 GeV. Further our results are compared with the recently reported data on K0 and K± inclusive cross sections. Also the possible contribution from F and F meson is studied around Ecm = 4.16 and 4.8 GeV.
