Minimal Model for Neutrino Masses and Mixings
Working in the framework of three chiral neutrinos with Majorana masses, we investigate a scenario first realized in an explicit model by Zee: that the neutrino mass matrix is strictly off-diagonal in the flavor basis, with all its diagonal entries precisely zero. This CP-conserving ansatz leads to two relations among the three mixing angles (θ1, θ2, θ3) and two squared mass differences. We imp...
متن کاملMinimal So(10) Grand Unification: Predictions for Proton Decay and Neutrino Masses and Mixings
Prospects for SO(10) as a minimal grand unification group have recently been heightened by several considerations such as the MSW resolution of the solar neutrino puzzle, baryogenesis, possibility for understanding fermion masses etc. I review the present status of the minimal SO(10) models with special emphasis on the predictions for proton lifetime and predictions for neutrino masses for the ...
متن کاملA Predictive Minimal Model for Neutrino Masses and Mixings
A model is considered in which the scale of the heavy singlet neutrinos is a few orders of magnitude below the grand unification scale and where righthanded vector bosons play still a negligible role. In a basis with diagonal upquark and Dirac-neutrino mass matrices it is assumed that the heavy neutrino mass matrix has only zero elements in its diagonal, in analogy to the light neutrino mass ma...
متن کاملNeutrino Masses and Mixings in a Predictive SO(10) Model with CKM CP Violation
It has recently been shown that a minimal SO(10) model with a single 10 and single 126 Higgs field breaking B-L symmetry predicts large solar and atmospheric mixings in agreement with observations if it is assumed that the neutrino mass obeys the type II seesaw formula. No additional symmetries need to be assumed for this purpose. Understanding CP violation in the renormalizable version of the ...
متن کاملProton Decay in a Minimal SUSY SO(10) Model for Neutrino Mixings
A minimal renormalizable SUSY SO(10) model with B-L symmetry broken by 126 Higgs field has recently been shown to predict all neutrino mixings and the ratio ∆m⊙/∆m 2 A in agreement with observations. Unlike models where B-L is broken by 16 Higgs, this model guarantees automatic R-parity conservation and hence a stable dark matter without any additional symmetry assumptions. In this paper, we di...
