Towards Precision Measurements of $γ$: CLEO-c's Pivotal Role
Strategies that utilise the interference effects within $B^{\pm} \to DK^{\pm}$ decays hold great potential for improving our sensitivity to the CKM angle $γ$. 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 $ψ(3770)$ datasets at CLEO-c. Results of such analyses involving the decay mode $D \to Kπππ$, and their importance in the context of LHCb, will be presented.
