The Neutrino Mass Matrix – From A 4 to Z 3
نویسنده
چکیده
With the recent experimental advance in our precise knowledge of the neutrino oscillation parameters, the correct form of the 3 × 3 neutrino mass matrix is now approximately known. I discuss how this may be obtained from symmetry principles, using as examples the finite groups A 4 and Z 3 , in two complete theories of leptons (and quarks). ——— Preprint version of talk at the 9th Adriatic Meeting in Dubrovnik (2003).

Near 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 کامل0 Consequences of a Z 2 Symmetry for Neutrino Oscillations
A Z 2L × Z 2R generation symmetry in the neutrino sector predicts the atmospheric neutrino mixing to be maximal, and the MNS matrix element U e3 to be zero, consistent with observations. Solar neutrino mixing may be maximal but is not required by the symmetry. Neutrino masses of the first two generations are predicted to vanish, providing a first approximation to the oscillation data. The conse...
متن کاملLarge or Small Angle MSW from Single Right - Handed Neutrino Dominance
In this talk we discuss a natural explanation of both neutrino mass hierarchies and large neutrino mixing angles, as required by the atmospheric neutrino data, in terms of a single right-handed neutrino giving the dominant contribution to the 23 block of the light effective neutrino matrix, and illustrate this mechanism in the framework of models with U(1) family symmetries. Sub-dominant contri...
متن کاملNeutrino Mass Matrix with Approximate Flavor Symmetry
Phenomenological implications of neutrino oscillations implied by recent experimental data on pattern of neutrino mass matrix are diss-cussed. It is shown that it is possible to have a neutrino mass matrix which shows approximate flavor symmetry; the neutrino mass differences arise from flavor violation in off-diagonal Yukawa couplings. Two modest extensions of the standard model, which can emb...
