摘要：

Because of the quantum correlation between the pair-produced D-0 and D-0 from the decay of the psi(3770), the time-integrated single and double tag decay rates depend on charm mixing amplitudes, doubly-Cabibbo-suppressed amplitudes, and the relative strong phase delta between D-0 and (D) over bar (0) decays to identical final states. Using 281 pb(-1) collected with the CLEO-c detector on the psi(3770) resonance, we measure the absolute branching fractions of D-0 decays to hadronic flavored states, CP eigenstates, and semileptonic final states to determine the relative strong phase cos delta and to limit the mixing amplitude y.
