%0 Journal Article %T Quantum Correlated Charm at Threshold and Inputs to Extractions of $¦Ã$ from $B$ Decays %A Roy A. Briere %J Physics %D 2014 %I arXiv %X 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 $\gamma$ ($\phi_3$) 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. %U http://arxiv.org/abs/1411.7327v2
