Abstract

Considering the constraints from the experimental data on μ→ eγ, μ→3e, μ-e conversion etc., we analyze the Lepton Flavor Violating decays ϕ(J/Ψ,Υ(1S)) → e⁺μ^-(μ⁺τ^-) in the scenarios of the minimal supersymmetric extensions of Standard Model with seesaw Mechanism. Numerically, there is parameter space that the LFV processes of J/Ψ(Υ)→μ⁺τ^- can reach the upper experimental bounds, meanwhile the theoretical predictions on μ→ eγ, μ→3e, μ-e conversion satisfy the present experimental bounds. For searching of new physics, Lepton Flavor Violating processes J/Ψ(Υ)→μ⁺τ^- may be more promising and effective channels.
