Search for lepton-flavor-violating $\tau$ decays into a lepton and a vector meson

Abstract

We search for lepton-flavor-violating 0 decays, where is an electron or muon and V 0 is one of the vector mesons K0 and ？ 0. We use 854 fb?1 of data collected with the Belle detector at the KEKB asymmetric-energy e+e? collider. No evidence for a signal is found in any decay mode, and we obtain 90% confidence
