$b \to s \gamma$ and CP violation in the MSSM

TL;DR

This paper investigates how the MSSM with large phases affects CP violation and finds that experimental constraints from $b o s \gamma$ decay limit observable CP violation effects.

Contribution

It demonstrates that in the CMSSM, experimental bounds on $b o s \gamma$ restrict the size of new CP violation contributions to undetectable levels.

Findings

Contributions to $\epsilon_{K}$ and $\epsilon_{B}$ are too small to detect.

Experimental $b o s \gamma$ constraints limit CP violation signals.

Large supersymmetric phases do not lead to observable CP violation within current bounds.

Abstract

In this work, we study possible new contributions to $\epsilon_{K}$ and $\epsilon_{B}$ in the MSSM with large supersymmetric phases. We show that, in the CMSSM, the constrains coming from the experimental measure of the $b \to s \gamma$ decay imply that these contributions are too small to be detected in CP violation experiments with the available sensitivity.
