Chiral fermions and AdS/CFT duality for a nonabelian orbifold

Abstract We present what we believe is the minimal three-family AdS/CFT model compactified on a nonabelian orbifold S 5 /( Q × Z 3 ). Nontrivial irreps of the discrete nonabelian group Q × Z 3 are identified with the 4 of SU (4) R symmetry to break all supersymmetries, and the scalar content of the model is sufficient to break the gauge symmetry to the standard model. According to the conformality hypothesis the progenitor SU (4) 3 × SU (2) 12 theory becomes conformally invariant at an infra-red fixed point of the renormalization group.
