Abstract :
We investigate three classes of supersymmetric models which can be obtained by breaking the chiral SU(2k + 3) gauge theories with one antisymmetric tensor and 2k − 1 antifundamentals. For N = 3, the chiral SU(2k)×SU(3)×U(1) theories break supersymmetry by quantum deformations of the moduli spaces in the strong SU(2k) gauge coupling limit. For N = 2, it is the generalization of the SU(5) × U(2) × U(1) model mentioned in the literature. Supersymmetry is broken by carefully choosing the quark-antiquark-doublet Yukawa couplings in this model. For N = 1, this becomes the well-known model discussed in the literature.
