摘要：
We analyze the SU(5) x U(1)' X U(1)4 X SO(10) X SU(4) superstring model with a spontaneously broken hidden sector down to SO(7) X SO(5) taking into account non-renormalizable superpotential terms up to eight order. As a result of the hidden sector breaking the "exotic" states get a mass and the "observable" spectrum is composed of the standard three families. In addition, Cabibbo mixing arises at sixth order and an improved fermion mass hierarchy emerges.
