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, down to SU(2k+3-N)×\timesSU(N), N≤\leq3. For N=3, the chiral SU(2k)\time sSU(3) theories break supersymmetry by the quantum deformations of the moduli spaces in the weak SU(3) gauge coupling limit. For N=2, in addition to the field content of the conventional SU(2k+1)×\timesSU(2) models, this model has 2k-1 SU(2) doublets an d one singlet field. The supersymmetry can also be broken once appropriate Yukawa couplings are added in the superpotential. For N=1, it is the well known model discussed in the literature.
