Lepton flavor violation two-body decays of quarkoniums
In this paper we firstly study various model-independent bounds on lepton flavor violation (LFV) in processes of $J/Ψ$, $Ψ'$ and $Υ$ two-body decays, then calculate their branch ratios % By using the constraints from other ways, we obtain %the indirect bounds of ${\rm Br} (J/Ψ,Ψ',Υ\to ll')$ in models of the leptoquark, $R$ violating MSSM and topcolor assisted technicolor(TC2) models.
