Towards Precision Measurements of $\gamma$: CLEO-c's Pivotal Role

Abstract

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 D meson decay structure is required. This essential information can be obtained from the quantum correlated $\psi(3770)$ datasets at CLEO-c. Results of such analyses involving the decay mode $D \to K\pi\pi\pi$, and their importance in the context of LHCb, will be presented.
