Direct and semi-direct approaches to lepton mixing with a massless neutrino
Journal of High Energy Physics
We discuss the possibility of enforcing a massless Majorana neutrino in the direct and semi-direct approaches to lepton mixing, in which the PMNS matrix is partly predicted by subgroups of a discrete family symmetry, extending previous group searches up to order 1535. We find a phenomenologically viable scheme for the semi-direct approach based on Q(648) which contains Δ(27) and the quaternion group as subgroups. This leads to novel predictions for the first column of the PMNS matrixdoi:10.1007/jhep06(2016)147 fatcat:ytipuyko3jg73e5llch4crvyze
