CP Violation in Supersymmetry with Effective Minimal Flavour Violation

TL;DR

This paper demonstrates that in supersymmetric models with Effective Minimal Flavour Violation, large CP-violating phases are compatible with current Electric Dipole Moment constraints, addressing the SUSY CP problem.

Contribution

It shows that all phases allowed by the flavour symmetry can be sizable without violating EDM constraints, unlike standard Minimal Flavour Violation.

Findings

All CP-violating phases can be large without EDM constraints.

Detailed analysis of one- and two-loop EDM contributions.

Predictions for CP asymmetries in B physics.

Abstract

We analyze CP violation in supersymmetry with Effective Minimal Flavour Violation, as recently proposed in arXiv:1011.0730. Unlike the case of standard Minimal Flavour Violation, we show that all the phases allowed by the flavour symmetry can be sizable without violating existing Electric Dipole Moment constraints, thus solving the SUSY CP problem. The EDMs at one and two loops are precisely analyzed as well as their correlations with the expected CP asymmetries in B physics.
