Neutrino Mixing and Leptonic CP Violation from $S_4$ Flavour and Generalised CP Symmetries

J. T. Penedo, S. T. Petcov, A. V. Titov

We consider a class of models of neutrino mixing with $S_4$ lepton flavour symmetry combined with a generalised CP symmetry, which are broken to residual $Z_2$ and $Z_2 \times H^ν_…
