Supersymmetry beyond minimal flavour violation

TL;DR

This paper reviews non-minimal flavour violation in the MSSM, exploring theoretical and experimental constraints, potential observables at colliders, and implications for supersymmetry breaking and new physics at high scales.

Contribution

It provides a comprehensive overview of non-minimal flavour violation sources, phenomenology, and their implications for supersymmetry and high-scale physics beyond minimal models.

Findings

Current data may hint at deviations from the Standard Model.

Flavour physics is highly sensitive to supersymmetry breaking mechanisms.

Identifies promising observables for future collider experiments.

Abstract

We review the sources and phenomenology of non-minimal flavour violation in the MSSM. We discuss in some detail the most important theoretical and experimental constraints, as well as promising observables to look for supersymmetric effects at the LHC and in the future. We emphasize the sensitivity of flavour physics to the mechanism of supersymmetry breaking and to new degrees of freedom present at fundamental scales, such as the grand unification scale. We include a discussion of present data that may hint at departures from the Standard Model.
