| dc.description | In an effective lagrangian approach [EM97] to new physics, the authors in ref. [HL99] pushed tau anomalous magnetic and electric dipole moments (AMDM and EDM) down to $10^{-11}$ and $10^{-25} e cm$ by using a Fritzsch-Xing lepton mass matrix ansatz. In this note, we find that, in this approach, there exists the connection between $τ$ AMDM and EDM and the lepton flavor mixing matrix. By using the current neutrino oscillation experimental results, we investigate the parameter space of lepton mixing angles to $τ$ AMDM and EDM. We can obtain the same or smaller bounds of $δa_τ$ and $d_τ$ acquired in ref. [HL99] and constrain $θ_l$ (the mixing angle obtained by long-baseline neutrino oscillation experiments) from $τ$ AMDM and EDM. | |
