SO(3) Gauge model for neutrino masses and oscillations
I mainly describe neutrino masses and oscillations in the gauge model with SO(3)F lepton flavor symmetry and with two Higgs triplets. It is shown how the maximal mixing between νμ and ντ neutrinos comes out naturally after spontaneous breaking of the symmetry. The nearly two-flavor mixing scenario is resulted naturally from an approximate permutation symmetry between the two Higgs triplets. The...
متن کاملNeutrino masses and oscillations
I summarize the status of three–neutrino oscillations that follow from combining the relevant world’s data. The discussion includes the small parameters α ≡ ∆m2 sol /∆m2 atm and sin2 θ13, which characterize the strength of CP violation in neutrino oscillations, the impact of oscillation data on the prospects for probing the absolute scale of neutrino mass in ββ0ν and the robustness of the neutr...
متن کاملFlavor Mixing, Quark Masses, Neutrino Masses and Neutrino Oscillations
We discuss first the flavor mixing of the quarks, using the texture zero mass matrices. Then we study a similar model for the mass matrices of the leptons. We are able to relate the mass eigenvalues of the charged leptons and of the neutrinos to the mixing angles and can predict the masses of the neutrinos. We find a normal hierarchy the masses are 0.004 eV, 0.01 eV and 0.05 eV. The atmospheric...

We find a normal hierarchy the masses are 0.004 eV, 0.01 eV and 0.05 eV. The atmospheric mixing angle is given by the mass ratios of the charged leptons and the neutrinos. We find 38 degree...
متن کاملNews on Neutrino Oscillations and Neutrino Masses
Recent results on neutrino oscillations and neutrino masses are presented. The most exciting news are the Super-Kamiokande measurements of atmospheric neutrinos, which show evidence for the neutrinos being massive. Various possible schemes for the neutrino masses are discussed.
