Abstract

Including the generalized CP symmetry, we have performed a comprehensive scan of leptonic mixing patterns that can be obtained from finite discrete groups with order less than 2000. Both the semidirect approach and its variant are considered. The lepton mixing matrices that can admit a good agreement with experimental data can be organized into eight different categories up to possible row and column permutations. These viable mixing patterns can be completely obtained from the discrete flavor groups Δ(6n2), D9n,3n(1), A5 and Σ(168) combined with CP symmetry. We perform a detailed analytical and numerical analysis for each possible mixing pattern. The resulting predictions for lepton mixing parameter, neutrinoless double beta decay, and flavored leptogenesis are studied.
