Abstract
We report the first observation of a manifestly violating effect in the decay mode. A large asymmetry was observed in the distribution of these decays in the -odd and -odd angle between the decay planes of the and pairs in the center of mass system. After acceptance corrections, the overall asymmetry is found to be . This is the largest -violating effect yet observed when integrating over the entire phase space of a mode and the first such effect observed in an angular variable.
