Query: Search for Lepton Flavor Violating tau Decays at B-factories   Lepton flavor violations in charged lepton give good signatures for the new
physics. We review recent searches for lepton flavor violation in tau decays at
B-factories. In these searches, optimization for background reduction is
important to obtain high sensitivity. No evidence for these decays is observed
and 90% confidence level upper limits have been set on the branching fractions
at the O(10^{-8}) level.
