Abstract
We present a model for the lepton sector, with horizontal-symmetry group, in which two of the Higgs doublets in an triplet of Higgs doublets have equal vacuum expectation values. The model makes well-defined predictions for the effective light-neutrino Majorana mass matrix. We show that those predictions are compatible with the experimental data.
