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

Abstract

In this work, we study possible new contributions to ${ϵ}_K$ and ${ϵ}_B$ 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.
