论文摘要
最近，已经提出了在Calabi-yau奇点上的D-branes模型的第一个实例，其中提出了超对称性将超对称性分解成稳定的真空吸尘器。该结构基于$ n $常规的系统，$ m = 1 $ branes放置在所谓（方向）八角形奇点的尖端。在本文中，我们表明该模型承认具有相同低能有效动态的大型$ M $概括。这打开了对几何形状的影响平滑的可能性，并且可以通过弱耦合的重力双重背景来沿着RG流（包括深IR）描述量规理论。还讨论了该结果在弦乐景观和Swampland程序的更广泛背景下的相关性。
Recently, the first instance of a model of D-branes at Calabi-Yau singularities where supersymmetry is broken dynamically into stable vacua has been proposed. This construction was based on a system of $N$ regular and $M=1$ fractional branes placed at the tip of the so-called (orientifolded) Octagon singularity. In this paper we show that this model admits a large $M$ generalization, having the same low energy effective dynamics. This opens up the possibility that the effect on geometry is smooth, and amenable to describing the gauge theory all along the RG flow, including the deep IR, in terms of a weakly coupled gravity dual background. The relevance of this result in the wider context of the string landscape and the Swampland program is also discussed.
