| 概要 | In light of a discrepancy of the direct CP violation in K→ππ decays, ε′/ε, we investigate gluino contributions to the electroweak penguin, where flavor violations are induced by squark trilinear couplings. Top-Yukawa contributions to ΔS=2 observables are taken into account, and vacuum stability conditions are evaluated in detail. It is found that this scenario can explain the discrepancy of ε′/ε for the squark mass smaller than 5.6 TeV. We also show that the gluino contributions can amplify B(K→πνν⎯⎯⎯), B(KS→μ+μ−)_eff and ΔA_CP(b→sγ). Such large effects could be measured in future experiments. |
