Neutrino Masses, Mixings in a Minimal SO(10) Model and Leptonic Flavor Violation
Abstract
The minimal SO(10) model with one 10 and one /line{126} Higgs can fit the neutrino masses and mixing angles. Recently, a detailed analysis shows that the fit of solar, atmospheric mixing angles and mass ratios in this very predictive minimal model requires the Kobayashi-Maskawa phase to be either 0 (Type I seesaw) or to be much larger than 100°(Type II seesaw). In this talk, we propose a parity symmetric SO(10) model with an additional 120 Higgs multiplet. The parity symmetry makes the Yukawa matrices hermitian and all the parameters in Higgs sector are real. The model is more predictive since the number of parameters is less than the original minimal model. I will elaborate the predictions of this more minimal model.
