Abstract

We present a new model of the lepton sector that uses a family symmetry A4A4

to make predictions for lepton mixing which are invariant under any

permutation of the three flavours. We show that those predictions

broadly agree with the experimental data, leading to a largish sin2θ12≳0.34, to |cosδ|≳0.7, and to |0.5−sin2θ23|≳0.08; cos δ   and 0.5−sin2θ23 are predicted to have identical signs.
