Higgs-Particle Interpretation of Narrowe+e−Resonances

We present a gauge model in which parity and ${\left[\mathrm{SU}\mathrm{}\right(2)\mathrm{}\otimes \mathrm{Y}]}_W$ are spontaneously broken. Three neutral Higgs particles couple directly to $e^{+}{e}^{-}$ (${\mu }^{+}{\mu }^{-}$) with coupling strengths proportional to a heavy-electron (muon) mass. Identification of two Higgs particles with $e^{+}{e}^{-}$ resonances at 3.105 and 3.695 GeV limits the two heavy-lepton masses to 1-3 GeV. The heavy leptons are not produced by ${\nu }_L$ beams, but have sequential signature in $e^{+}{e}^{-}$ production.
