Lepton flavor violating $Z\to l_1^{+}{l}_2^{-}$ decay in the general two Higgs Doublet model

Abstract

We calculate lepton flavor violating Z -> l^+ l^- decay in the framework of the general two Higgs Doublet model. In our calculations we used the constraints for the Yukawa couplings \bar{\xi}^{D}_{N,\tau e} and \bar{\xi}^{D}_{N,\tau\mu} coming from the experimental result of muon electric dipole moment and upper limit of the BR(\mu -> e\gamma). We observe that it is possible to reach the present experimental upper limits for the branching ratios of such Z decays in the model III.
