Abstract
Experimentally viable lepton mixing parameters can be predicted in so-called direct flavour models with Majorana neutrinos using groups as a flavour group. In direct models, in which the flavour group is broken to a subgroup in the neutrino sector, mixing angles and Dirac CP phase are purely predicted from symmetry. General predictions of direct models with flavour groups are that all mixing angles are fixed up to a discrete choice and that the Dirac CP phase is or ; Furthermore, the middle column of the mixing matrix is trimaximal which yields the sum rule depending on the Dirac phase. These predictions of lepton mixing parameters are compatible with recent global fit results or will be tested experimentally in the near future. It is the first time that such predictions have been obtained model-independently for an infinite series of groups.
