| 英文摘要 | 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 nu(mu) and nu(tau) 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 hierarchy between the neutrino mass-squared differences, which is needed for reconciling both solar and atmospheric neutrino data, leads to an almost maximal mixing between nu(e) and nu(mu) neutrinos. Thus the model favors the intriguing bi-maximal mixing scenario, The three Majorana neutrino masses are allowed to be nearly degenerate and large enough to play a significant cosmological role. The model can also lead to interesting phenomena on lepton-flavor violations via the SO(3)(F) gauge interactions. |
