Charged-lepton mass matrix and nonzero θ13 with TeV scale new physics

We provide an explicit structure of the charged-lepton mass matrix which is 2-3 symmetric except for a single breaking of this symmetry by the muon mass. We identify a flavor symmetric limit for the mass matrices where the first generation is decoupled from the other two in the charged-lepton sector while in the neutrino sector the third generation is decoupled from the first two generations. The leptonic mixing in the symmetric limit can be, among other structures, the bimaximal or the tri-bimaximal mixing. Symmetry breaking effects are included both in the charged-lepton and the neutrino sector to produce corrections to the leptonic mixing and explain the recent θ₁₃ measurements. A model that extends the standard model by three right-handed neutrinos, an extra Higgs doublet, and two singlet scalars is introduced to generate the leptonic mixing.
