Neutrino Mass Matrix with Approximate Flavor Symmetry

چکیده
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 embed the resulting neutrino mass matix have also been discussed. The data [1, 2, 3, 4, 5] from solar and atmospheric neutrino experiments provide evidence for neutrino mass and mixing. As such lepton flavor is violated providing evidence for physics beyond the standard model (SM). The present experimental data can be explained by neutrino oscillations with mass squared differences and mixing angles having following best fit values [6]

متن کاملNeutrinos With Z3 Symmetry and New Charged-Lepton Interactions
An approximate Z3 family symmetry is proposed for leptons which results in a neutrino mass matrix with sin 2θatm = 1 and tan 2 θsol = 0.5, but the latter value could easily be smaller. A generic requirement of this approach is the appearance of three Higgs doublets at the electroweak scale, resulting in possibly observable flavor violating leptonic decays, such as μ → eee and μ → eγ. ——————————...
متن کاملLarge Neutrino Flavor Mixings and Lepton Mass Matrices 1 Morimitsu TANIMOTO
Recent atmospheric neutrino data at Super-Kamiokande suggest the near-maximal flavor mixing. Models for the lepton mass matrix, which give the near-maximal flavor mixing, are discussed in this report. Mass matrix models are classified according to the mechanism providing the large flavor mixing, and those are reviewed briefly. " Naturalness " of the mass matrix is also discussed in order to sel...
متن کاملModel-Independent Analysis of Tri-bimaximal Mixing – a Softly-Broken Hidden or an Accidental Symmetry?
To address the issue of whether tri-bimaximal mixing (TBM) is a softly-broken hidden or an accidental symmetry, we adopt a model-independent analysis in which we perturb a neutrino mass matrix leading to TBM in the most general way but leave the three texture zeros of the diagonal charged lepton mass matrix unperturbed. We compare predictions for the perturbed neutrino TBM parameters with those...
متن کاملPlato’s Fire and the Neutrino Mass Matrix
With the accumulation of many years of solar and atmospheric neutrino oscillation data, the approximate form of the 3 × 3 neutrino mixing matrix is now known. The theoretical challenge is to understand where this mixing matrix comes from. Recently, a remarkable fact was discovered that for a specific pattern of the neutrino mass matrix at a high scale, any flavor-changing radiative correction w...
