Modelling tri-bimaximal neutrino mixing
We model tri-bimaximal lepton mixing from first principles in a way that avoids the problem of the vacuum alignment characteristic of such models. This is achieved by using a softly broken A4 symmetry realized with an isotriplet fermion, also triplet under A4. No scalar A4-triplet is introduced. This represents one possible realization of general schemes characterized by the minimal set of eith...
متن کاملBimaximal Neutrino Mixing and Neutrino Mass Matrix
We show that the bimaximal neutrino mixing pattern suggested by the solar and atmospheric neutrino data can be derived from the maximal, symmetric , four neutrino mixing in the limit that one of the neutrinos is made heavy. Imposing the constraints of no neutrinoless double beta decay and a 20% hot dark matter component of the universe leads to a three neutrino mass matrix recently suggested by...
متن کاملStable bimaximal neutrino mixing pattern
The data from the various neutrino experiments indicate a bimaximal mixing among three neutrino generations. The atmospheric neutrino puzzle requires a near maximal mixing between a pair of neutrinos [1]. The solar neutrino puzzle has various possible solutions but the large angle MSW solution is favoured [2]. As the mass squared difference required for these two solutions differ by about few o...
متن کاملTri-bimaximal and bimaximal neutrino mixing from discrete sym- metries
— The neutrino oscillation data are well explained by the tri-bimaximal pattern. Recently it has been shown that also the bimaximal pattern could be a very good starting point in order to describe the lepton mixing. In this paper I review both the flavour structures and then I present an explicit example. 1. – The lepton mixing matrix The solar and the atmospheric neutrino anomalies are well ex...
متن کاملTri - bimaximal Neutrino Mixing and θ 13
We propose an extension of tri-bimaximal mixing to include a non-zero reactor angle θ13 while maintaining the tri-bimaximal predictions for the atmospheric angle θ23 = 45 o and solar angle θ12 = 35 . We show how such tri-bimaximalreactor mixing can arise at leading order from realistic GUT models with nonAbelian discrete family symmetry spontaneously broken by flavons with vacuum alignment, bas...
