CP violation leads to a difference between the parameters $g^+$ and $g^-$ describing the energy distributions of the charged pions produced in the $K^+ \to��^0 ��^0 ��^+$ and $K^- \to ��^0��^0 ��^-$ decays. We study the difference $(g^+ - g^-)$ as a function of the relative contributions from the QCD-penguin and the electroweak-penguin diagrams. We find that the combination of these contributions in $(g^+ - g^-)$ is very similar to the corresponding one defining the parameter $��'$ in the $K_L \to 2��$ decays. This observation allows a determination of the value of $(g^+ - g^-)$, using data on $��'$. |
