Impact on $\gamma {\varphi }_3$ from CLEO-c Using CP-tagged $D\toK_{S,L}ππ$ Decays

Eric White, Qing He

Precision determination of the CKM angle $\gamma /{\varphi }_3$ depends upon constraints on charm mixing amplitudes, measurements of doubly-Cabibbo suppressed amplitudes and relative phases, and…
