This Feynman diagram shows the neutral kaon ${\displaystyle K^{0}}$ turning into ${\displaystyle {\overline {K}}^{0}}$ by means of the exchange of a pair of W bosons. This diagram, together with the rotated diagram (shown below), give the leading terms to CP violation.

The image below shows the same diagram, emphasizing the structure of the Kaons.
