Non-Abelian Discrete Symmetries and Neutrino Masses: Two Examples
Two recent examples of non-Abelian discrete symmetries (S3 and A4) in understanding neutrino masses and mixing are discussed.
متن کاملNeutrino masses and non abelian horizontal symmetries
Recently neutrino experiments have made very significant progresses and our knowledge of neutrino masses and mixing has considerably improved. In a model independent Monte Carlo approach, we have examined a very large class of textures, in the context of non abelian horizontal symmetries; we have found that neutrino data select only those charged lepton matrices with left-right asymmetric textu...
متن کاملNeutrino masses from discrete gauge symmetries
We investigate a model with an extra Z2 gauge symmetry in the Standard Model. The symmetry gives a structure to the mass matrix for the neutrinos. With two extra Higgs singlets and two extra singlet right-handed neutrinos we can build a model that fits the requirements of the MSW-solution of the Solar neutrino problem. With a third singlet right-handed neutrino it is also possible to have a 10 ...
متن کاملNon-Abelian Discrete Flavor Symmetries
This is an incomplete survey of some non-Abelian discrete symmetries which have been used recently in attempts to understand the flavor structure of leptons and quarks. To support such symmetries, new scalar particles are required. In some models, they are very massive, in which case there may not be much of a trace of their existence at the TeV scale. In other models, they are themselves at th...
متن کاملSymmetries and Neutrino Masses
The role of symmetries in understanding neutrino masses and mixing is discussed, with special attention on the application of two non-Abelian discrete groups, S3 and A4.
