Consistent with experimental data

Abstract

Flavour groups have been extensively used to explain the pattern of mixing in the lepton sector. In combination with generalised CP six observables of the lepton sector can be predicted: three mixing angles and three phases. We present the predictions made from using A5 as a flavour group.
