Abstract

The analysis of quantum-correlated D-D decays produced at the ψ(3770) resonance gives unique insight into quantities such as strong-phase differences and coherence factors. Knowledge of these parameters is invaluable for measurements of the CKM-angle γ (ϕ₃) in B → DK decays. Results from CLEO-c analyses performed at the ψ(3770) resonance in a variety of decay channels are reported, and their consequences for the determination of γ is assessed. Future prospects are given for extensions to the present studies.
