Abstract The first direct observation of time-reversal (T) violation in the B B ‾ system has been reported by the BaBar Collaboration, employing the method of Banuls and Bernabeu. Given this, we generalize their analysis of the time-dependent T-violating asymmetry ( A T ) to consider different choices of CP tags for which the dominant amplitudes have the same weak phase. As one application, we find that it is possible to measure departures from the universality of sin ⁡ ( 2 β ) directly. If sin… CONTINUE READING
