Two/Three-Flavor Oscillation and MSW/JUST-SO Solution of Neutrinos in the SO(3) Gauge Model
نویسنده
چکیده
Three interesting scenarios for neutrino mixing, i.e., (i) small-large mixing scenario, (ii) nearly bi-maximal mixing scenario and (iii) three-flavor oscillation scenario, are investigated in a model with gauged SO(3) lepton flavor symmetry. These three scenarios are in connection with three possible assignments of the maximal CP-violating phase after spontaneous symmetry breaking of SO(3). Three Majorana neutrino masses in all scenarios can be nearly degenerate. In the scenarios (ii) and (iii), masses of the neutrinos are allowed to be large enough to play a significant cosmological role. In the scenario (i) the fraction Ων/Ωm is bounded to be Ων/Ωm < (4− 10)% for Ωm = (1.0 − 0.4) and h = 0.6. PACS numbers: 12.15F, 11.30H

Two/Three-Flavor Oscillation and MSW/Vacuum Oscillation Solution of Neutrinos in the SO(3) Gauge Model
Three interesting scenarios for neutrino mixing, i.e., (i) small-large mixing scenario, (ii) nearly bi-maximal mixing scenario and (iii) three-flavor oscillation scenario, are analyzed in connection with three possible assignments of the maximal CP-violating phase after spontaneous symmetry breaking of SO(3) in the model with gauged SO(3) lepton flavor symmetry. As a consequence, it is found th...
متن کاملSolar and Atmospheric Neutrino Oscillations and Lepton Flavor Violation in Supersymmetric Models with the Right - handed Neutrinos
Taking the solar and the atmospheric neutrino experiments into account we discuss the lepton flavor violating processes, such as τ → μγ or μ → eγ, in the minimal supersymmetric standard model with the right-handed neutrinos (MSSMRN) and the supersymmetric SU(5) GUT with the righthanded neutrinos (SU(5)RN). The predicted branching ratio of μ → eγ in the MSSMRN with the MSW large angle solution i...

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 کاملJust-So Oscillation: as Just as MSW?
The neutrino long wavelength (just-so) oscillation is reconsidered as a solution to the solar neutrino problem. In the light of the presently updated results of the four solar neutrino experiments, the data fit in the just-so scenario substantially improves and becomes almost as good as in the MSW scenario. Surprising result of our analysis is that best fit is achieved when the oscillation occu...
