Abstract

We begin with an E₈× E₈ Heterotic model broken to an SU(5)_gauge × U(1)_X and a twin SU(5)_gauge × U(1)_X, where one SU(5) and its spectrum is identified as the visible sector while the other can be identified as a hidden twin sector. In both cases we obtain the minimal supersymmetric standard model (MSSM) spectrum after Wilson-line symmetry-breaking enhanced by a low energy R-parity and ℤ₄^R symmetry. We argue that there will not be any observable proton decay in this model
