Gluino-mediated electroweak penguin with flavor-violating trilinear couplings

Motoi Endo, Toru Goto, Teppei Kitahara +3

In light of a discrepancy of the direct $CP$ violation in $K\to \pi \pi$ decays, ${\epsilon }^{\prime }/{\epsilon }_K$, we investigate gluino contributions to the electroweak penguin, where flavo…
