0 Large Lepton Flavor Mixings in SU ( 6 ) × SU ( 2 ) R Model
The lepton masses and mixings are studied on the basis of string inspired SU(6) × SU(2)R model with global flavor symmetries. Provided that sizable mixings between lepton doublets L and Higgsino-like fields Hd with even R-parity occur and that seesaw mechanism is at work in the neutrino sector, the model can yield a large mixing angle solution with tan θ12, tan θ23 = O( √ λ) (λ = 0.22), which i...

متن کاملLarge Lepton Mixings from Continuous Symmetries
Within the broad context of quark-lepton unification, we investigate the implications of broken continuous family symmetries which result from requiring that in the limit of exact symmetry, the Dirac mass matrices yield hierarchical masses for the quarks and charged leptons, but lead to degenerate light neutrino masses as a consequence of the seesaw mechanism, without requiring hierarchical rig...
متن کاملLarge Lepton Mixings Induced by Sterile Neutrino
We assume that the mass matrix of active neutrinos has hierarchical form with small mixings, similar to quark mass matrix. We show that the large mixings between ν µ and ν τ as well as between ν e and certain combination of ν µ and ν τ required by the present data can appear due to the presence of a sterile neutrino state. Two realizations of this possibility are considered: (i) Large flavor mi...
متن کاملLarge Neutrino Flavor Mixings and Lepton Mass Matrices 1 Morimitsu TANIMOTO
Recent atmospheric neutrino data at Super-Kamiokande suggest the near-maximal flavor mixing. Models for the lepton mass matrix, which give the near-maximal flavor mixing, are discussed in this report. Mass matrix models are classified according to the mechanism providing the large flavor mixing, and those are reviewed briefly. " Naturalness " of the mass matrix is also discussed in order to sel...
