Abstract
For some of the vectorlike weak currents such as the one suggested by Fritzsch et al., the radiative decay of heavy leptons allows us to test it for arbitrary values of parameters in e +e − annihilation at presently available energies, provided that the charged heavy lepton is identified with the U-particle. Existing data already constrain the mass of the neutral lepton N M to be ≲ 8 GeV.
