Abstract: We search for lepton-flavor-violating decays, where ℓ is an electron or muon and is one of the vector mesons , ϕ, ω, and . We use of data collected with the Belle detector at the KEKB asymmetric-energy collider. No evidence for a signal is found in any decay mode, and we obtain 90% confidence level upper limits on the individual branching fractions in the range . [Copyright &y& Elsevier]
