Obtaining the Neutrino Mixing Matrix with the Tetrahedral Group
نویسنده
چکیده
(This parametrization may differ slightly from others in that we take detV23 = detV12 = −1.) The error bars are such that θ31 is consistent with 0, in which case the CP violating phase e iφ does not enter. We could suppose either that the entries in V represent a bunch of meaningless numbers (possibly varying from domain to domain in the universe as advocated by some theorists of great sophistication) or that they point to some deeper structure or symmetry. It is natural to imagine that there is a family symmetry [2] linking the three lepton families. Starting with the standard model we assign (all fermionic fields are left handed) the lepton doublets

Flavor Symmetry for Quarks and Leptons
Present data on neutrino masses and mixing favor the highly symmetric tribimaximal neutrino mixing matrix which suggests an underlying flavor symmetry. A systematic study of non-abelian finite groups of order g ≤ 31 reveals that tribimaximal mixing can be derived not only from the well known tetrahedral flavor symmetry T ≡ A4, but also by using the binary tetrahedral symmetry SL2(F3) which does...
متن کاملRealizations of Neutrino Tribimaximal Mixing Without and With Corrections
In an improved application of the tetrahedral symmetry A4 first introduced by Ma and Rajasekaran, supplemented by the discrete symmetry Z3 as well as supersymmetry, a two-parameter form of the neutrino mass matrix is derived which exhibits the tribimaximal mixing of Harrison, Perkins, and Scott. This form is the same one obtained previously by Altarelli and Feruglio, and the inverse of that obt...
متن کاملNear Tribimaximal Neutrino Mixing with ∆(27) Symmetry
The discrete subgroup ∆(27) of SU(3) has the interesting multiplication rule 3×3 = 3̄ + 3̄ + 3̄, which is used to obtain near tribimaximal neutrino mixing. Using present neutrino oscillation data as input, this model predicts that the effective mass mee measured in neutrinoless double beta decay will be 0.14 eV. The non-Abelian discrete subgroup ∆(12) of SU(3) [1], more familiarly known as A4 [2, ...

متن کاملTribimaximal neutrino mixing from a supersymmetric model with A4 family symmetry
In the supersymmetric seesaw model of neutrino masses, augmented by the nonAbelian discrete tetrahedral symmetry A4, a specific pattern of neutrino mixing is automatically generated if one of the three heavy singlet neutrino superfields acquires a nonzero vacuum expectation value. This pattern turns out to be exactly that of tribimaximal mixing, i.e. sin θ23 = 1/2, sin 2 θ12 = 1/3, and sin 2 θ1...
