Abstract

We propose a phenomenological model of lepton mixing and CP violation based on the flavor democracy of charge leptons and the mass degeneracy of neutrinos. A nearly bimaximal flavor mixing pattern, which is favored by current data on atmospheric and solar neutrino oscillations, emerges naturally from this model after explicit symmetry breaking. The rephasing-invariant strength of CP or T violation can be as large as one percent, leading to significant probability asymmetries between \ensuremathν_\ensuremathμ\ensuremath→\ensuremathν_e and \ensuremathν_\ensuremathμ\ensuremath→\ensuremathν_e (or \ensuremathν_e\ensuremath→\ensuremathν_\ensuremathμ) transitions in the long-baseline neutrino experiments.
