Search for baryon and lepton number violating decays of the tau lepton

We have searched for five decay modes of the τ lepton that simultaneously violate lepton and baryon number: τ-→p̄γ, τ-→p̄π0, τ-→p̄η, τ-→p̄2π0, and τ-→p̄π0η. The data used in the search were collected with the CLEO II detector at the Cornell Electron Storage Ring. The integrated luminosity of the dat...

description We have searched for five decay modes of the τ lepton that simultaneously violate lepton and baryon number: τ-→p̄γ, τ-→p̄π0, τ-→p̄η, τ-→p̄2π0, and τ-→p̄π0η. The data used in the search were collected with the CLEO II detector at the Cornell Electron Storage Ring. The integrated luminosity of the data sample is 4.7 fb-1, corresponding to the production of 4.3 × 106 τ+τ- events. No evidence is found for any of the decays, resulting in much improved upper limits on the branching fractions for the two-body decays and first upper limits for the three-body decays. ©1999 The American Physical Society.
