SUSY Phenomenology of KKLT Flux Compactifications

TL;DR
This work analyzes SUSY phenomenology in KKLT flux compactifications, where the MSSM soft terms follow a hierarchical pattern with $m_{MSSM} \ll m_{3/2} \ll m_{moduli}$. The authors perform a comprehensive phenomenological study, applying collider and flavor constraints and ensuring correct electroweak symmetry breaking, then assessing compatibility with the observed dark matter abundance. They find that a TeV-scale MSSM is compatible with all constraints and can accommodate both low and high $tanβ$, with the spectrum typically above 1 TeV and with heavy gravitino/moduli alleviating cosmological problems. The results illustrate the viability and testable predictions of KKLT-inspired SUSY phenomenology for future collider and dark matter experiments.
Abstract
We study SUSY phenomenology of the KKLT (Kachru-Kallosh-Linde-Trivedi) scenario of string theory compactifications with fluxes. This setup leads to a specific pattern of soft masses and distinct phenomenological properties. In particular, it avoids the cosmological gravitino/moduli problems. Remarkably, the model allows for the correct abundance of SUSY dark matter consistently with all experimental constraints including the bound on the Higgs mass, b-->s gamma, etc. This occurs for both small and large tan beta, and requires the SUSY spectrum above 1 TeV.
