Lepton flavor violation two-body decays of quarkoniums

Abstract

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