Phys. Rev. Lett. 77, 2612–2615 (1996)Three-Family SO(10) Grand Unification in String TheoryReceived 30 May 1996; published in the issue dated 23 September 1996 The construction of a supersymmetric SO(10) grand unification with 5 left-handed and 2 right-handed families in the four-dimensional heterotic string theory is presented. The model has one SO(10) adjoint Higgs field. The SO(10) current algebra is realized at level 3. © 1996 The American Physical Society URL:
