Zee model and phenomenology of lepton sector

Abstract

The virtual effects of the Zee charged scalar boson on the lepton-family-number (LFN) violating processes are studied. We obtain the constraints on the individual Yukawa coupling constants of the Zee boson to leptons. Using these constraints, we predict the upper bounds on the muonium-antimuonium conversion probability, the branching fractions of the LFN violating decays such as $\tau \to e\gamma$, $\tau \to \mu \gamma$, ${\tau }^{-}\to {\mu }^{+}{e}^{-}{e}^{-}$ and $\tau \to e^{+}{\mu }^{-}{\mu }^{-}$. The contribution of the Zee boson to the muon anomalous magnetic moment is also considered
