Abstract

We produce five flavour models for the lepton sector. All five models

fit perfectly well — at the 1σ level — the existing data on the neutrino

mass-squared differences and on the lepton mixing angles. The models

are based on the type I seesaw mechanism, on a TeX

symmetry for each lepton flavour, and either on a (spontaneously

broken) symmetry under the interchange of two lepton flavours or on a

(spontaneously broken) CP symmetry

incorporating that interchange — or on both symmetries simultaneously.

Each model makes definite predictions both for the scale of the neutrino

masses and for the phase δ in lepton mixing; the fifth model also predicts a correlation between the lepton mixing angles θ ₁₂ and θ ₂₃.
