Neutrino oscillations and mixings with three flavors

Abstract

Global fits to all data of candidates for neutrino oscillations are presented in the framework of a three-flavor model. The analysis excludes mass regions where the MSW effect is important for the solar neutrino problem. The best fit gives ${\theta }_1\approx 28.9^{\circ },{\theta }_2\approx 4.2^{\circ },{\theta }_3\approx 45.0^{\circ },m_2^2-m_1^2\approx 2.87\cdot 10^{-4}e{V}^2$, and $m_3^2-m_2^2\approx 1.11e{V}^2$ indicating essentially maximal mixing between the two lightest neutrino mass eigenstates.
