摘要：

We have searched for decays that violate both lepton and baryon number using data collected by the Belle detector at the KEKB asymmetric e(+)e(-) collider. No signals are found in tau(-) -> (p) over bar gamma, tau(-) -> (p) over bar pi(0), tau(-) -> (A) over bar pi(-), and tau(-) -> A pi(-) and we set upper limits on the branching fractions of B(tau(-) -> (p) over bar gamma) < 3.0 x 10(-7), B(tau(-) -> <(p)over bar>pi(0)) < 6.5 x 10(-7), B(tau(-) -> <(A)over bar>pi(-)) 1.3 x 10(-7), and B(tau(-) -> A pi(-)) < 0.70 x 10(-7) at the 90% confidence level.
