Recently, CP violation has been observed in the B0 system. The parameter measured, , is analogous to ϵ for the K0 system since it can be explained entirely by B0- mixing. We label as observables that measure directly CP violation in the decay amplitude. A large value for one of these observables would be the definitive evidence against the superweak theory. Problems and prospects for detecting are discussed.
