Unified QCD evolution equations and the dominant behaviour of structure functions at low x

Tri-bimaximal mixing is a specific lepton mixing ansatz, which has been shown to account very successfully for the established neutrino oscillation data. Working in a particular basis (the 'circulant basis'), we identify three independent symmetries of tri-bimaximal mixing, which we exploit to set the tri-bimaximal hypothesis in context, alongside some simple, phenomenologically interesting CP -conserving and CP -violating generalisations.

We re-fit for the neutrino mass-squared difference ∆m 2 in the threefold maximal (ie. 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 < ∼ 1000 km, they are highly significant for atmospheric experiments, suppressing naturally ν e mixing and enhancing ν µ − ν τ mixing, so as to effectively remove the experimental distinction between threefold maximal and twofold maximal ν µ − ν τ 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 ∆m 2 ≃ (0.98 ± 0.30 0.23 ) × 10 −3 eV 2 .
