SUSY-breaking as the origin of flavour violation

TL;DR

This paper reviews how radiative flavor violation in the MSSM, driven by SUSY-breaking terms, impacts flavor physics constraints and can explain certain CP phenomena with TeV-scale SUSY masses.

Contribution

It highlights the role of SUSY-breaking terms as the sole source of flavor violation and explores their implications for flavor observables and CP violation.

Findings

Constraints from Kaon mixing and b->s+gamma are satisfied at ~1 TeV SUSY masses.

Neutral Higgs penguins significantly affect B_s->mu^+mu^- decay.

SUSY-breaking as the origin of flavor violation can explain observed CP phases.

Abstract

In this article I review the consequences of radiative flavor violation (RFV) in the Minimal Supersymmetric Standard Model (MSSM). In this framework the trilinear supersymmetry (SUSY)-breaking terms are the only source of flavor violation. Constraints on the parameter space come from Kaon mixing and b->s+gamma and are satisfied for SUSY masses of the order of 1 TeV. In addition, neutral Higgs penguins significantly contribute to B_s->mu^+mu^- and are capable of explaining the observed CP phase in the B_s system.
