D0barD0 Quantum Correlations, Mixing, and Strong Phases

Abstract

Due to the quantum correlation between the pair-produced D0 and D0bar 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 D0 and D0bar 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 D0 decays to hadronic flavored states, CP eigenstates, and semileptonic final states to determine the relative strong phase, cos delta, of the K- pi+ final state and to limit the mixing amplitude y. The results presented in this document are preliminary.
