If you have a question about this talk, please contact Steve Chun Hay Kom. We present a realistic grand unified theory of flavor based on SO(10) x PSL (2,7), where the quarks and leptons in the 16 of SO(10) are assigned to the complex triplet representation of the discrete family symmetry PSL (2,7). The flavons on the other hand are assigned to the sextet and anti-triplet representations. Using a D-term vacuum alignment mechanism, one flavon sextets is aligned along the 3-3 direction leading to the third family Yukawa couplings, while other sextets are aligned along the neutrino flavor symmetry preserving directions leading to the possibility of tri-bimaximal neutrino mixing via the type II see-saw mechanism. The structure of the neutrino mixing is thus a direct reflection of how the family symmetry gets broken. Some phenomenological implications of this setup are discussed.
