A Texture of Leptons for the Koide and Alikhanov relations

Abstract

Koide and Alikhanov proposed intriguing empirical relations among charged-lepton masses and neutrino mass splittings, respectively. We present mass-matrix textures that realise these relations and can jointly account for the observed lepton mixing angles, while yielding predictive correlations among them and the neutrino CP phases.
