Quantum Correlated Charm at Threshold and Inputs to Extractions of $\gamma$ from $B$ Decays

Abstract

The basic physics of quantum-correlated D0, D0bar pairs produced at threshold via decays of the $\psi (3770)$ is introduced. The connection to extractions of the CKM angle $\gamma$ (${\varphi }_3$) from $B$ decays is emphasized throughout. Recent quantum correlation results from BESIII and CLEO-c are then summarized before closing with a discussion of selected issues.
