$ε'/ε$ And Anomalous Gauge Boson Couplings

We study $ε'/ε$ in the Standard Model and $ε'/ε$ due to anomalous $WWγ$ and $WWZ$ interactions %using recent result on the top quark mass from CDF. as a function of the top quark mass. In the Standard Model, $ε'/ε$ is in the range $10^{-3} \sim 10^{-4}$ for the central value of top quark mass reported by CDF. The anomalous gauge couplings can have large contributions to the $CP$ violating $I=2$ amplitude in $K \rightarrow ππ$. Within the allowed regions for the anomalous gauge couplings, $ε'/ε$ can be dramatically different from the standard model prediction.
