Dipole moments of charged leptons in the THDM-III with Textures

Abstract

We study the magnetic and weak magnetic dipole moments of charged leptons in the framework of the Two Higgs Doublet Model type III (THDM-III) with four zero textures. We first analyze the possibility that the discrepancy between the experimental measurements and the theoretical prediction of the muon anomalous magnetic dipole moment ($a_{\mu }$) in the Standard Model (SM) can be explained in the context of the model and then find values for the parameters of the THDM-III: neutral and charged Higgs boson masses ($m_H$, $m_{H^{\pm }}$), mixing angles ($\alpha ,\beta$), CP-violating angles ${\theta }_1,{\theta }_2$ and an additional parameter arising from the mass matrix (${\gamma }_f$), for which a correspondence between theory and experiment is possible. We use $a_{\mu }^{THDM-III}$ and current low energy processes $K-\bar{K}$ mixing, $B_s^0\to \mu \bar{\mu }$, $\tau \to \mu \mu \bar{\mu }$, $\mu \to ee\bar{e}$, $\tau \to \mu \gamma$, $\tau \to e\gamma$, $\mu \to e\gamma$, $b\to s\gamma$, $B\to D(D^{\ast })\tau \nu$ and the rare higgs decay $h\to \tau \mu$ in order to determine the allowed parameter space of THDM-III and from these we give a prediction for the magnetic and weak magnetic dipole moment of charged leptons, in particular of the $\tau$ lepton. The obtained magnetic dipole moment of the $\tau$ lepton is of the order of $\mathcal{O}(10^{-8}-10^{-7})$ and the weak magnetic is of the order $\mathcal{O}(10^{-10}-10^{-7})$.
