Abstract

We estimate the PMNS (Pontecorvo-Maki-Nakagawa-Sakata) matrix in terms of neutrino and charged lepton mixing given as U_{\rm PMNS}=V_{\rm lep}^†(θ₁₃) U_ν(θ₂₃, θ₁₂), based on a new (emergent) global lepton flavor symmetry. The neutrino and charged lepton mass matrices have simple textures. The resulting U_{\rm PMNS} gives excellent agreement with experimental data (including |U_e3|≃ 0.16).
