# SU(3) Flavour Symmetries and CP Violation

## TL;DR

This paper explores how SU(3) flavour symmetry models, which spontaneously break CP symmetry, can address SUSY flavour and CP violation issues, predicting observable effects like EDMs and meson mixing that constrain SUSY parameters.

## Contribution

It demonstrates how SU(3) flavour symmetry models can simultaneously explain CP violation and restrict SUSY parameter space through correlations among observables.

## Key findings

- Constraints on SUSY parameters from meson mixing
- Predictions of correlated EDM and LFV signals
- Potential to distinguish models via CP violation observables

## Abstract

In order to satisfy current FCNC and CP violation bounds, SUSY flavour structures cannot be generic. An interesting solution to these SUSY Flavour and CP Problems lies on the use of an SU(3) family symmetry which spontaneously breaks CP symmetry. Typical observables of such a model are electric dipole moments and LFV processes. In addition, these models can give contributions to CP violation in neutral meson mixing. We show how the latter can be used to restrict the allowed SUSY parameter space, and induce correlations between LFV and EDM predictions.
