Abstract
We use the unitarity sum to rederive in a simple way an explicit formula for the mixing phase in terms of , , , and . We then present a systematic study of the condition imposed by (or ) invariance and unitarity on the relative phase and strength of the mixing. It is shown that the departure from invariance in the system is, in principle, directly demonstrable through the measurement of the mixing phase in . The connection between the phase discrepancy and the breakdown of microscopic reversibility is also discussed. Finally, two possible graphical representations for the mixing parameters which exhibit directly the condition imposed by unitarity and time-reversal invariance on the relative phases and strengths of the mixing are given.
