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 as a function of the top quark mass. In the standard model, ε’/ε is in the range ${10}^{\mathrm{-}3}$–${10}^{\mathrm{-}4}$ for the central value of the top quark mass reported by the CDF. The anomalous gauge couplings can have large contributions to the CP-violating I=2 amplitude in K→ππ. Within the allowed regions for the anomalous gauge couplings, ε’/ε can be dramatically different from the standard model prediction.
