Abstract

Neutrino oscillations as solutions of the solar neutrino problems and the atmospheric neutrino deficits may restrict neutrino mass squared differences and mixing angles in the three-neutrino mixing scheme. Currently we have several solutions depending on the interpretation of the solar neutrino problem. Combining the neutrino oscillation solutions and a mass matrix ansatz, we investigate the neutrino mass bounds and find a possible leptonic CP-violating rephasing-invariant quantity J_CP^l≤0.012 for the large mixing angle MSW and just-so vacuum oscillation solutions, and J_CP^l≤0.0013 for the small mixing angle MSW solution.
