Neutrino oscillations from warped flavor symmetry: predictions for long baseline experiments T2K, NOvA and DUNE
Here we study the pattern of neutrino oscillations emerging from a previously proposed warped model construction incorporating $Δ(27)$ flavor symmetry. In addition to a complete description of fermion masses, the model predicts the lepton mixing matrix in terms of two parameters. The good measurement of $θ_{13}$ makes these two parameters nearly proportional, leading to an approximate one-parameter description of neutrino oscillations. There is a sharp fourfold degenerate correlation between $δ_{CP}$ and the atmospheric mixing angle $θ_{23}$, so that maximal $θ_{23}$ also implies maximal leptonic CP violation. The predicted electron neutrino and anti-neutrino appearance probabilities indicate that the model should be tested at the T2K, NO$ν$A and DUNE long baseline oscillation experiments.
