Description
Lepton-flavor violating (LFV) decay in tau (and also in D, and B) is
expected to be very small in the Standard Model, even taking into
account the effect of neutrino mixing. Therefore, the observation of
such decays would be clear evidence of new physics. The production
rate of tau and D pairs at B factory is comparable to that of B meson
pairs and hence B factories are also excellent tau/charm factories.
Many LFV decay modes have been searched for at the B factories. We
present the current status of searches for tau LFV decays as well as D
and B LFV decays. Some of the upper limits are now reaching to range
predicted by some new physics models.
