For solar neutrinos the large angle MSW effect in tribimaximal mixing accounts for the experimental data, predicting average suppressions ⟨ ⟨ P e e ⟩ ⟩ ≃ ≃ 1 3 in the Sudbury Neutrino Observatory (SNO) and ⟨ ⟨ P e e ⟩ ⟩ ≃ ≃ 5 9 in lower energy solar neutrino experiments (and in long baseline reactor neutrino experiments). The bimaximally mixed ν ν 3 in tribimaximal mixing accounts for the factor of two suppression ⟨ ⟨ P μ μ μ μ ⟩ ⟩ ≃ ≃ 1 2 observed for atmospheric muon-neutrinos (and confirmed in long-baseline accelerator experiments). Near-zero ν ν e appearance in a ν ν μ μ beam is predicted in exact tribimaximal mixing ( | U e 3 | 2 = 0 ), and this has been strongly ruled out by modern reactor neutrino experiments. Further characteristic predictions of tribimaximal mixing – e.g. for very long baseline ν ν μ μ and ν ν τ τ vacuum survival probabilities P μ μ μ μ = P τ τ τ τ ≃ ≃ 7 18 – will be extremely hard to test experimentally.
