Electron EDM and LFV decays in the light of Muon (g-2) _ with U (2) flavor symmetry

Abstract We study the interplay of New Physics (NP) among the lepton magnetic moment, the lepton flavor violation (LFV) and the electron electric dipole moment (EDM) in light of recent data of the muon (g-2) _ (g-2) μ. The NP is discussed in the leptonic dipole operator with the U (2) flavor symmetry of the charged leptons, where possible CP violating phases of the three family space are taken into account. It is remarked that the third-family contributes significantly to the LFV decay, e μ→eγ, and the electron EDM. The experimental upper-bound on e μ→eγ decay gives a severe constraint on the parameters of the flavor model. The predicted electron EDM is rather large due to the CP violating phases in the three family space. In addition, we also study (g-2) ₄, (g-2) e, τ of the electron and tauon, and EDMs of the muon and tauon as well as the e τ→eγ and τ→μγ decays. The R L τR→μLγ decay is predicted to be close to the experimental upper-bound.
