Neutrino Masses and Flavour Symmetry
The problem of neutrino masses and mixing angles is analysed in a class of supersymmetric grand unified models, with SO(10) gauge symmetry and global U(2) flavour symmetry. Adopting the seesaw mechanism for the generation of the neutrino masses, one obtains a mass matrix for the left–handed neutrinos which is directly related to the parameters of the charged sector, while the unknown parameters...
متن کاملSymmetry and Neutrino Masses and Mixings
Based on a universal seesaw mass matrix model with three scalars φi, and by assuming an S3 flavor symmetry for the Yukawa interactions, the lepton masses and mixings are investigated systematically. In order to understand the observed neutrino mixing, the charged leptons (e, μ, τ) are regarded as the 3 elements (e1, e2, e3) of S3, while the neutrino masseigenstates are regarded as the irreducib...
متن کاملOn the origin of neutrino flavour symmetry
We study classes of models which are based on some discrete family symmetry which is completely broken such that the observed neutrino flavour symmetry emerges indirectly as an accidental symmetry. For such “indirect” models we discuss the D-term flavon vacuum alignments which are required for such an accidental flavour symmetry consistent with tri-bimaximal lepton mixing to emerge. We identify...

متن کاملTri-bimaximal Neutrino Mixing and Quark Masses from a Discrete Flavour Symmetry
We build a supersymmetric model of quark and lepton masses based on the discrete flavour symmetry group T , the double covering of A4. In the lepton sector our model is practically indistinguishable from recent models based on A4 and, in particular, it predicts a nearly tri-bimaximal mixing, in good agreement with present data. In the quark sector a realistic pattern of masses and mixing angles...
