Models of dynamical supersymmetry breaking from a SU(2k + 3) gauge model
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. ForN = 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.
