Constraints on LVS Compactifications of IIB String Theory

TL;DR

This paper analyzes various LVS compactifications of type IIB string theory, concluding that a sequestered version with anomaly-mediated soft terms is favored after applying all constraints.

Contribution

It identifies a specific LVS compactification that remains viable and favored, emphasizing the role of anomaly mediation in soft term generation.

Findings

Sequestered LVS models are consistent with all constraints.

Anomaly mediation is the dominant mechanism for soft terms in the favored model.

Other LVS variants are less compatible with combined theoretical and phenomenological constraints.

Abstract

We argue that once all theoretical and phenomenological constraints are imposed on the different versions of the Large Volume Scenario (LVS) compactifications of type IIB string theory, one particular version is favored. This is essentially a sequestered one in which the soft terms are generated by Weyl anomaly and RG running effects. We also show that arguments questioning sequestering in LVS models are not relevant in this case.
