SU(4)_c x SU(2)_L x SU(2)_R model from 5D SUSY SU(4)_c x SU(4)_{L+R}

Abstract

We investigate supersymmetric $SU(4{)}_c\times SU(4{)}_{L+R}$ theory in 5 dimensions whose compactification on a $S^{(1)}/Z_2$ orbifold yields N=1 supersymmetric $SU(4{)}_c\times SU(2{)}_L\times SU(2{)}_R$ supplemented by a $\text{tl}U(1)$ gauge symmetry. We discuss how the $\mu$ problem is resolved, a realistic Yukawa sector achieved, and a stable proton realized. Neutrino masses and oscillations are also briefly discussed.
