We have observed 1522 neutrino events with a μ- secondary and 8 events with a μ+ secondary from a beam consisting mostly of neutrinos. The μ+ events are consistent in number and kinematic properties with beam contamination by ν̅ μ. This experiment sees no evidence for production of heavy positively charged leptons. Assuming a coupling constant equal to the universal Fermi constant and a branching ratio to muons B=0.3, our 90% confidence lower limit corresponds to MY+≳8.4 GeV/c^2.
