- 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.
