A(4) family symmetry and quark-lepton unification

King, S.F. and Malinsky, M. (2007) A(4) family symmetry and quark-lepton unification Physics Letters B, 645, (4), pp. 351-357. (doi:10.1016/j.physletb.2006.12.006).

Record type: Article


We present a model of quark and lepton masses and mixings based on A4 family symmetry, a discrete subgroup of an SO(3) flavour symmetry, together with Pati–Salam unification. It accommodates tri-bimaximal neutrino mixing via constrained sequential dominance with a particularly simple vacuum alignment mechanism emerging through the effective D-term contributions to the scalar potential.
