在长寿命亚稳态真空中的动力学超对称破缺是唯象上可行的可能性。这条相对未被探索的途径导致了许多动力学超对称破缺的新模型。在这里，我们提出了一个令人惊讶的简单类模型与亚稳定动力学超对称性破缺：= 1超对称QCD，与大量的口味。虽然这些理论是强耦合的，我们明确地证明了亚稳态真空的存在，通过使用自由磁对偶。模型构建的挑战，如大的风味对称性和R对称性的缺乏，很容易适应这些理论。它们的简单性也表明，破缺的超对称性在超对称场论和弦真空中是普遍存在的。
Dynamical supersymmetry breaking in a long-lived meta-stable vacuum is a phenomenologically viable possibility. This relatively unexplored avenue leads to many new models of dynamical supersymmetry breaking. Here, we present a surprisingly simple class of models with meta-stable dynamical supersymmetry breaking: = 1 supersymmetric QCD, with massive flavors. Though these theories are strongly coupled, we definitively demonstrate the existence of meta-stable vacua by using the free-magnetic dual. Model building challenges, such as large flavor symmetries and the absence of an R-symmetry, are easily accommodated in these theories. Their simplicity also suggests that broken supersymmetry is generic in supersymmetric field theory and in the landscape of string vacua.
