We have searched for five decay modes of the tau lepton that simultaneously
violate lepton and baryon number: tau(-) --> (p) over bar gamma, tau(-) --
> (p) over bar pi(0), tau(-) --> (p) over bar eta, tau- --> (p) over bar 2
pi(0), and tau- --> (p) over bar pi(0)eta. 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 t
o the production of 4.3 x 10(6) tau(+)tau(-) events. No evidence is found f
or any of the decays, resulting in much improved upper limits on the branch
ing fractions for the two-body decays and first upper limits for the three-
body decays. [S0556-2821(99)50209-9].
