Predicting Lepton Flavor Mixing from $\Delta(48)$ and Generalized CP Symmetries

Understand

We propose to understand the mixing angles and CP-violating phases from the $\Delta(48)$ family symmetry combined with the generalized CP symmetry.

• A model-independent analysis is performed by scanning all the possible symmetry breaking chains.
• We find a new mixing pattern with only one free parameter, excellent agreement with the observed mixing angles can be achieved and all the CP-violating phases are predicted to take nontrivial values.
• This mixing pattern is testable in the near future neutrino oscillation and neutrinoless double-beta decay experiments.
