Title A Redetermination of the Neutrino Mass-Squared Difference in Trimaximal Mixing with Terrestrial Matter Effects
Abstract We re-fit for the neutrino mass-squared difference delta m squared in the threefold maximal (i.e. tri-maximal) mixing scenario using recent CHOOZ and SUPER-K data, taking account of matter effects in the Earth. While matter effects have little influence on reactor experiments and proposed long-baseline accelerator experiments with L equal to or less than 1000Km, they are highly significant for atmospheric experiments, suppressing naturally neutrino-electron mixing and enhancing neutrino-muon - neutrino-tauon mixing, so as to effectively remove the experimental distinction between threefold maximal and twofold maximal neutino-muon - neutrino-tauon mixing. Threefold maximal mixing is fully consistent with the CHOOZ and SUPER-K data, and the best-fit value for the neutrino mass-squared difference is delta m squared ~bar (0.98 +bar 0.30 over 0.23) x 10 to the minus three eV squared.
