Models of Dynamical Supersymmetry Breaking from a SU(2k+3) Model

TL;DR

This paper explores three classes of supersymmetric models derived from chiral SU(2k+3) gauge theories, demonstrating how supersymmetry breaking occurs through quantum deformations and specific Yukawa couplings in different parameter regimes.

Contribution

It introduces new classes of supersymmetric models based on SU(2k+3) gauge theories and analyzes their supersymmetry breaking mechanisms across different N values.

Findings

Supersymmetry is broken via quantum deformations in the strong coupling limit.

Models generalize known SU(5)×U(2)×U(1) and other configurations.

Specific Yukawa couplings induce supersymmetry breaking in N=2 models.

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)$\times$SU(3)$\times$U(1) theories break supersym metry by the 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)$\times$U(2)$\times$U(1) model mentioned in the literature. Supersymmetry is broken by carefully choosing the q uark-antiquark-doublet Yukawa couplings in this model. For N=1, this becomes the well-known model discussed in the literature.
