CP-Violating Observables in Tagged $D^0$--${\bar{D}}^0$ Decays

Abstract

We perform a systematic study of CP-violating observables in \ddbar\ decays. We show that given a final state, which may be a CP eigenstate or not, all the observables can in principle be measured if decay-time information is available and if, for CP non-eigenstates, both decay rates into $f$ and $\bar{f}$ are considered. As an illustration of our analysis we discuss an effective superweak scenario.
