چکیده
The recent experimental results on neutrino oscillation and on muonium-antimuonium conversion require extension of the minimal 3-3-1 model. We review the constraints imposed to the model by those measurements and suggest a pattern of leptonic mixing, with charged leptons in a non-diagonal basis, which accounts for the neutrino physics and circumvents the tight muonium-antimuonium bounds on the model. We also illustrate a scenario where this pattern could be realized.

We investigate constraints imposed by lepton mixing and muonium-antimuonium conversion in a minimal version of 3 − 3 − 1 model. Demanding agreement with recent results on neutrino oscillation we show that minimal 3 − 3 − 1 has to be extended in order to correctly accommodate its mixing pattern. On the other hand muonium-antimuonium conversion puts a lower bound on the vector bilepton mass in a ...

In the minimal 3-3-1 model charged leptons come in a non-diagonal basis. Moreover the Yukawa interactions of the model lead to a non-hermitian charged lepton mass matrix. In other words, the minimal 3-3-1 model presents a very complex lepton mixing. In view of this we check rigorously if the possible textures of the lepton mass matrices allowed by the minimal 3-3-1 model can lead or not to the ...

We present a model of the lepton masses and flavor mixing based on the discrete group S 4 ⊗Z 2. In this model, all the charged leptons and neutrinos are assigned to the 3 α representation of S 4 in the Yamanouchi bases. The charged lepton and neutrino masses are mainly determined by the vacuum expectation value structures of the Higgs fields. Our model predicts a nearly tri-bimaximal lepton fla...
