Abstract:A 5D SU(7) family unification model with two spinor representations of SO(14) is presented. The fifth dimension is compactified on S1/Z2×Z2′. The orbifolding is used to obtain 4D SO(10) chiral fermions. The 4D grand unification group is the flipped SU(5)×U(1). The doublet–triplet splitting through the missing partner mechanism is achieved. Also, fermion mass matrices are considered.
Keywords:Family unification  Orbifold  SU(7) grand unification  Mass matrix
