Recently, the standard model prediction of $\epsilon'/\epsilon$ was
improved, and a discrepancy from the experimental results was reported
at the $2.9\sigma$ level. We study the charging contributions to $Z$
penguin especially with the vacuum stability constraint. The vacuum
decay rate is investigated, and it is shown that the discrepancy can be
explained if super particles are lighter than $4-6\mbox{TeV}$.
Correlations with $\mathcal{B}(K_L\to\pi^0\nu\bar{\nu})$ is also
discussed. We also study the gluino contributions to $Z$ penguin.
