Sequestering in String Theory

TL;DR

This paper investigates how warped compactifications in type IIB string theory can enable sequestering, which is crucial for flavor-blind supersymmetry breaking, by analyzing gravity and gauge theory perspectives.

Contribution

It demonstrates that strongly warped backgrounds can achieve sequestering, providing insights into soft term patterns in KKLT compactifications.

Findings

Sequestering is absent in unwarped backgrounds.

Strongly warped compactifications can successfully sequester.

Subtle effects can disrupt sequestering in compactifications.

Abstract

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.
