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 \ensuremathθ₁\ensuremath≈28.9\ifmmode^∘\else\textdegree\fi, \ensuremathθ₂\ensuremath≈4.2\ifmmode^∘\else\textdegree\fi, \ensuremathθ₃\ensuremath≈45.0\ifmmode^∘\else\textdegree\fi, m₂²\ensuremath-m₁²\ensuremath≈2.87\ifmmode×\else\texttimes\fi10^\ensuremath-4eV², and m₃²\ensuremath-m₂²\ensuremath≈1.11eV² indicating essentially maximal mixing between the two lightest neutrino mass eigenstates.
