Description

We construct a supersymmetric standard model in the context of the Z_{12-I} orbifold compactification of the E_8 x E_8' heterotic string theory. The gauge group is SU(3)_c x SU(2)_L x U(1)_Y x U(1)^4 x [SO(10) x U(1)^3]' with sin^2\theta_W^0 = 3/8. We obtain three families of SO(10) spinor-like chiral matter states, and Higgs doublets. All exotic states are exactly vector-like under the standard model gauge symmetry. There are numerous neutral singlets, many of which get VEVs such that only the standard model gauge symmetry survives and desired Yukawa couplings can be generated at lower energies . In particular, all vector-like exotic states achieve superheavy masses and the R-parity can be preserved.
