Description
We report results of a search for tau lepton decays strongly suppressed
in the Standard Model based on the world-largest data sample
accumulated with the Belle detector at the KEKB asymmetric-energy
e+e- collider. The decays include: lepton flavor and lepton number
violating tau decays into a lepton (e or mu) and two charged mesons
(K or pi), lepton flavor violating decays into a lepton (e or mu)
and a photon as well as lepton and baryon number violating tau decays
into a Lambda and a charged meson (K or pi). The sensitivity to the
branching fractions is significantly improved compared to our previous results
and in some cases reaches O(10^{-8}).
