Discrete symmetries:<br />

CP violation<br />

Mix<strong>in</strong>g <strong>in</strong> the system of the neutral mesons (cont'd)<br />

These CP eigenstates are nearly perfect mixtures of<br />

the flavour eigenstates.<br />

ε is related to the amount of CP-violation <strong>in</strong> the<br />

kaon system (the prob. for decays <strong>in</strong>to the “wrong”<br />

number of pions).
