heal.abstract	We propose an extension of the Standard Model inspired by the E-8 x E-8 Heterotic String. In order that a reasonable effective Lagrangian is presented we neglect everything else other than the ten-dimensional N = 1 supersymmetric Yang-Mills sector associated with one of the gauge factors and certain couplings necessary for anomaly cancellation. We consider a compactified space-time M-4 X B-0/Z(3), where B-0 is the nearly Kahler manifold SU(3)/U(1) x U(1) and Z(3) is a freely acting discrete group on B-0. Then we reduce dimensionally the E8 on this manifold and we employ the Wilson flux mechanism leading in four dimensions to an SU(3)3 gauge theory with the spectrum of a N = 1 supersymmetric theory. We compute the effective four-dimensional Lagrangian and demonstrate that an extension of the Standard Model is obtained with interesting features including a conserved baryon number and fixed tree level Yukawa couplings and scalar potential. The spectrum contains new states such as right-handed neutrinos and heavy vector-like quarks. (C) 2011 Elsevier B.V. All rights reserved.	en
