Abstract :
We consider effects of CP violating phases in μ and At parameters in the effective supersymmetric standard model on B→Xsl+l− and ϵK. Scanning over the MSSM parameter space with experimental constraints including edm constraints from Chang-Keung-Pilaftsis (CKP) mechanism, we find that the Br(B→Xsl+l−) can be enhanced by upto ∼85% compared to the standard model (SM) prediction, and its correlation with Br(B→Xsγ) is distinctly different from the minimal supergravity scenario. Also we find 1≲ϵK/ϵKSM≲1.4, and fully supersymmetric CP violation in KL→ππ is not possible. Namely, |ϵKSUSY|≲O(10−5) if the phases of μ and At are the sole origin of CP violation.
