CP-violating observables in tagged D0D0 decays

We perform a systematic study of CP-violating observables in D0D0 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 f are considered. As an illustration of our analysis we discuss an effective superweak scenario.
