我们研究隔离，在几个高规模的调解机制的味盲超对称性破缺的先决条件，在IIB型弦理论的紧致化。我们发现，尽管在未扭曲的背景中通常不存在隔离，但强烈扭曲的紧化确实很容易隔离。AdS/CFT对偶描述的共形隔离在我们的分析中起着重要的作用，我们建立隔离工程的重力侧和规范理论侧。我们特别注意可以破坏隔离的微妙的紧化效应。我们的结果是朝着实现一个有吸引力的模式软条款的KKLT紧化。
We study sequestering, a prerequisite for flavor-blind supersymmetry breaking in several high-scale mediation mechanisms, in compactifications of type IIB string theory. We find that although sequestering is typically absent in unwarped backgrounds, strongly warped compactifications do readily sequester. The AdS/CFT dual description in terms of conformal sequestering plays an important role in our analysis, and we establish how sequestering works both on the gravity side and on the gauge theory side. We pay special attention to subtle compactification effects that can disrupt sequestering. Our result is a step toward realizing an appealing pattern of soft terms in a KKLT compactification.
