Orbifolded SU(7) and unification of families
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.
