Discrete symmetries:<br />
CP violation<br />
Mix<strong>in</strong>g <strong>in</strong> the system of the neutral mesons (cont'd)<br />
ε is related to the Hamiltonian of the kaon system:<br />
The off-diagonal elements are given by amplitudes<br />
for the transition between the two kaons:<br />
The amplitude is proportional to a product of four<br />
CKM matrix elements of the form<br />
This allows for complex values <strong>in</strong> the Hamiltonian<br />
matrix CP violation.
