摘要：
Models which do not preserve N = 1 space-time SUSY are constructed in the framework of tensoring of N = 2 minimal superconformal theories quotiented by discrete symmetries. We concentrate on those models based on the standard (l = lBAR) affine invariants, and as quotient groups we use the Z(k+2) symmetry groups of the minimal theories at level k. In our analysis we investigate the way in which the usual generalized GSO projection must be modified in order to incorporate discrete torsions responsible for the N = 1 space-time breaking. We also determine the number of massless 27's and 27BAR's of E6, and the number of chiral superfields transforming as singlets under E6. A discussion on the massless spectrum of a specific model reveals some interesting phenomenological implications.
