Tackling the SUSY flavour & CP problem - SUGRA versus SU(3)

TL;DR

This paper compares supergravity-based solutions and SU(3) flavour symmetry approaches to the SUSY flavour and CP problem, highlighting the potential advantages of flavour symmetries in providing testable predictions.

Contribution

It demonstrates that SU(3) flavour symmetry can match or outperform supergravity methods in addressing SUSY flavour and CP issues, with added testable implications.

Findings

SU(3) flavour symmetry can mimic supergravity solutions

Flavour symmetries may offer better solutions with testable predictions

Potential for future experimental tests of flavour symmetry models

Abstract

We comment on the power of the 'standard' solutions to the SUSY flavour and CP problem based on supergravity and its derivates like mSUGRA in comparison to the flavour symmetry approach. It is argued that flavour symmetries, and SU(3) in particular, can not only mimic the situation in supergravity frameworks in this respect, but sometimes do even better providing at the same time a further link between the soft and Yukawa sectors, that could be testable at future experimental facilities.
