Examining the Geometrical Model with Inverted Mass Hierarchy for Neutrinos
arXiv:hep-ph/0701083 · doi:10.1103/PhysRevD.75.096005
Abstract
The comprehensive analyses are presented in the model with the inverted mass hierarchy for neutrinos, which follows from a geometrical structure of a (1+5) dimensional space-time where two extra dimensions are compactified on the T^2/Z_3 orbifold. The model gives two large lepton flavor mixings due to the S3 structure in the (1+5) dimensional space-time. It also predicts the lightest neutrino mass as m_3=(1-50)\times 10^{-5}eV and the effective neutrino mass responsible for neutrinoless double beta decays as <m>_{ee}\simeq 50 meV. The low energy CP violation, J_{CP} could be 0.02. On the other hand, the observed baryon asymmetry in the present universe is produced by the non-thermal leptogenesis, which works even at the reheating temperature TR=10^{4}-10^{6}GeV. The correlation between the baryon asymmetry and the low energy CP violation is examined in this model.
