Neutrino Mixing and Leptogenesis in Type-II Seesaw Scenarios with Left-Right Symmetry
arXiv:0704.3838 · doi:10.1016/j.physletb.2007.11.028
Abstract
We propose two Type-II seesaw scenarios for the neutrino mass matrix in the left-right symmetric model, in which the Higgs triplet Yukawa coupling matrix takes the appealing Friedberg-Lee texture. We show that the nearly tri-bimaximal neutrino mixing pattern, which is especially favored by current neutrino oscillation data, can be obtained from both scenarios. We also show that the cosmological baryon number asymmetry can naturally be interpreted in these two scenarios via the flavor-independent leptogenesis mechanism.
