Abstract

Motivated by dimensional deconstruction, we propose a model of tribimaximal neutrino mixing based on A4×A4 symmetry. In this model, the two triplet symmetry-breaking fields of conventional A4 models are taken to transform under different A4 group factors, but are not distinguished by any other quantum numbers. An additional bi-triplet flavon field breaks A4×A4 to its diagonal subgroup. If the bi-triplet transforms under an additional Z3 symmetry, we show that one can construct a general, renormalizable superpotential that yields the desired pattern of symmetry breaking. We identify the features that this model has in common with a deconstructed 5D theory in which A4is a subgroup of a continuous gauged flavor symmetry in the bulk.
