Remark about the violation parameter

Only the interference of the violating amplitude, , with the allowed, , amplitude, remains after integrating over the entire three-pion phase space. The interference of the allowed, , with the violating amplitude, can be safely neglected. Similar to the evaluation of we can write:

Since only the amplitude contributes, and by neglecting violation in the decay amplitude, we can simply write:

Any violation different from the pure mixing alters only the imaginary part of . Such a violation comes from the interference of the decay amplitude with the mixing amplitude.
