Flavour symmetries and SUSY soft breaking in the LHC era

TL;DR

This paper demonstrates that a realistic flavour symmetry can address both the supersymmetric flavour problem and the Standard Model flavour problem simultaneously, providing testable predictions such as the electron EDM.

Contribution

It introduces a flavour symmetry framework that solves key SUSY and SM flavour issues without ad hoc adjustments, and predicts observable effects like the electron EDM.

Findings

Flavour symmetry models can resolve the SUSY flavour and CP problems.

Predicted electron EDM values can distinguish between different flavour models.

Departures from Standard Model expectations are testable at the LHC and future experiments.

Abstract

The so-called supersymmetric flavour problem does not exist in isolation to the Standard Model flavour problem. We show that a realistic flavour symmetry can simultaneously solve both problems without ad hoc modifications of the SUSY model. Furthermore, departures from the SM expectations in these models can be used to discriminate among different possibilities. In particular we present the expected values for the electron EDM in a flavour model solving the supersymmetric flavour and CP problems.
