Precision determination of the CKM angle $\gamma/\phi_3$ depends upon constraints on charm mixing amplitudes, measurements of doubly-Cabibbo suppressed amplitudes and relative phases, and studies of charm Dalitz plots tagged by flavor or CP…
The analysis of quantum-correlated $D-\bar{D}$ decays produced at the $\psi(3770)$ resonance gives unique insight into quantities such as strong-phase differences and coherence factors. Knowledge of these parameters is invaluable for…
The most sensitive method to measure the CKM angle gamma is to exploit interference in B(+/-)->DK(+/-) decays, with the D-meson decaying to a hadronic final state. The analysis of quantum-correlated decays of the psi(3770) at CLEO-c…
The 818 fb^-1 dataset collected at the \psi(3770) resonance in the CLEO-c detector offers unique possibilities for measuring strong-phase differences in neutral D decays. We report results for D decays to K_S pi+ pi- and K_S K+ K-. The…
Strategies that utilise the interference effects within B -> DK decays hold great potential for improving our sensitivity to the CKM angle gamma. However, in order to exploit fully this potential, knowledge of parameters associated with the…
Measurements of D0 meson strong-phase parameters in quantum-correlated psi(3770) -> D0 D0bar decays by the CLEO collaboration are presented. These measurements play an important role in the determination of the unitarity triangle angle…
Quantum-correlated measurements of the decay $D^{0} \to K^{0}_{\rm S}\pi^{+}\pi^{-}\pi^{0}$ are performed using a data sample corresponding to an integrated luminosity of 818 pb$^{-1}$ collected at the $\psi(3770)$ resonance by the CLEO-c…
We perform quantum-correlated measurements of the decay $D \to K^{0}_{\rm S}\pi^{+}\pi^{-}\pi^{0}$ using a data sample corresponding to an integrated luminosity of 0.82 fb$^{-1}$ collected at the $\psi(3770)$ resonance by the CLEO-c…
The strong-phase differences between D0 and D0bar decays to common final states are crucial parameters in the determination of the CKM angle gamma from B to DK modes. The first quantum-correlated measurements of these parameters in several…
We exploit the quantum coherence between pair-produced D0 and D0bar in psi(3770) decays to study charm mixing, which is characterized by the parameters x and y, and to make a first determination of the relative strong phase \delta between…
Strategies that utilise the interference effects within $B^{\pm} \to DK^{\pm}$ decays hold great potential for improving our sensitivity to the CKM angle $\gamma$. However, in order to exploit fully this potential, detailed knowledge of the…
Quantum-correlated psi(3770)->DDbar decays collected by the CLEO-c experiment are used to perform measurements of F+, the fractional CP-even content of the self-conjugate decays D->pi+pi-pi0 and D->K+K-pi0. Values of 0.973+/-0.017 and…

We report the results of the Monte-Carlo study of the method to determine the CKM angle phi3 using Dalitz plot analysis of D0 decay from B->DK process. Our main goal is to find the optimal strategy for a model-independent phi3 extraction.…

We exploit the quantum coherence between pair-produced D0 and D0bar in psi(3770) decays to study charm mixing and to make a first measurement of the relative strong phase \delta between D0 -> K+pi- and D0bar -> K+pi-. Using 281 pb^-1 of…
Due to the presence of 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…
We investigate the decays $D^0\to\pi^-\ell^+\nu$ and $D^0\to K^-\ell^+ \nu$, where $\ell$ is $e$ or $\mu$, using approximately 7 ${\rm fb}^{-1}$ of data collected with the CLEO III detector. We find $R_0\equiv {\cal B}(D^0\to…
We present an updated study of charm mixing and the relative strong phase between doubly Cabibbo-suppressed D0 --> K+pi- and Cabibbo-favored D0bar --> K+pi- decay amplitudes using 3 x 10^6 quantum-correlated D0D0bar pairs from 818 pb^-1 of…
