Abstract

Because of the quantum correlation between the pair-produced D⁰ and from the decay of the ψ(3770), the time-integrated single and double tag decay rates depend on charm mixing amplitudes, doubly-Cabibbo-suppressed amplitudes, and the relative strong phase δ between D⁰ and decays to identical final states. Using 281 pb^-1 collected with the CLEO-c detector on the ψ(3770) resonance, we measure the absolute branching fractions of D⁰ decays to hadronic flavored states, CP eigenstates, and semileptonic final states to determine the relative strong phase cos δ and to limit the mixing amplitude y.
