Renormalization-Group Effects in the SO(3) Gauge Model With Nearly Degenerate Neutrino Masses and Bi-maximal Mixing

Abstract

The renormalization-group effects on the scenario with nearly degenerate mass and bi-maximal mixing of neutrinos are analyzed. As a consequence, we explicitly show in the SO(3) gauge model that the renormalization-group effects could modify the fitting values of the relevant basic parameters of the model, but leave the nearly bi-maximal mixing scenario to remain stable for reconciling both solar and atmospheric neutrino data. The approximately degenerate Majorana neutrino masses are allowed to be large enough to play a significant cosmological role without conflicting with the current neutrinoless double beta decay.
