Within the context of the E 8 × E 8 heterotic superstring compactified on a smooth Calabi‐Yau threefold with an SU (4) gauge instanton, we show the existence of simple, realistic N = 1 supersymmetric vacua that are compatible with low energy particle physics. The observable sector of these vacua has gauge group SU (3) C × SU (2) L × U (1) Y × U (1) B ‐ L , three families of quarks and leptons, each with an additional right‐handed neutrino , two Higgs‐Higgs conjugate pairs, a small number of uncharged moduli and no exotic matter .
