Search for Neutrinoless $\tau$ Decays Involving ${\pi }^0$ or $\eta$ Mesons

CLEO Collaboration, G. Bonvicini et al

We have searched for lepton family number violating decays of the $\tau$ lepton using final states with an electron or a muon and one or more ${\pi }^0$ or $\eta$ mesons but no neutrinos. The…
