We study (orientifolded) toric Calabi-Yau singularities in search for D-brane configurations which lead to dynamical supersymmetry breaking at low energy. By exploiting dimer techniques we are able to determine that while most realizations lead to a Coulomb branch instability, a rather specific construction admits a fully stable supersymmetry breaking vacuum. We describe the geometric structure that a singularity should have in order to host such a construction, and present its simplest example, the Octagon.

超对称破缺真空的二聚体、定向折叠和稳定性

我们研究（定向折叠的）复曲面 Calabi-Yau 奇点，以寻找导致动态超对称在低能量下破缺的 D 膜配置。通过利用二聚体技术，我们能够确定，虽然大多数实现会导致库仑支不稳定，但相当具体的构造允许完全稳定的超对称破真空。我们描述了奇点应该具有的几何结构，以便承载这样的结构，并展示其最简单的例子，八边形。
