我们考虑了Intriigator，Seiberg和Shih(ISS)的介稳N=1 QCD模型，该模型通过在超势中加入重子项而变形。这种简单的形变导致亚稳真空的近似R对称性自发破缺。然后我们测量SU(5)F的味道，并将其与标准模型(SM)的母规范对称性进行鉴定。这实现了超对称破缺的直接调解，而不需要额外的信使部分。参数的合理选择会产生正确顺序的伽吉诺质量。最后，我们推测整个“ISS×SM”模型应该被解释为一个(未知的)渐近自由理论的磁性对偶。
We consider the metastable N=1 QCD model of Intriligator, Seiberg and Shih (ISS), deformed by adding a baryon term to the superpotential. This simple deformation causes the spontaneous breaking of the approximate R-symmetry of the metastable vacuum. We then gauge the flavour SU(5)fand identify it with the parent gauge symmetry of the Standard Model (SM). This implements direct mediation of supersymmetry breaking without the need for an additional messenger sector. A reasonable choice of parameters leads to gaugino masses of the right order. Finally, we speculate that the entire “ISS × SM” model should be interpreted as a magnetic dual of an (unknown) asymptotically free theory.
