dc.description.abstractWe study an extension of the standard model based on the flavor symmetry A(4) only. Neutrino Majorana mass terms arise from a dimension five operator and charged lepton masses from renormalizable Yukawa couplings. We introduce three Higgs doublets that belong to one triplet irreducible representation of A(4). We study the most general A(4)-invariant scalar potential and the phenomenological consequences of the model. We find that the reactor angle could be as large as sin(2)theta(13max)similar to 0.03, while the atmospheric mixing angle theta(23) is close to maximal, sin(2)theta(23)=1/2.en_US
