Impact on $γϕ_3$ from CLEO-c Using CP-tagged $D\toK_{S,L}ππ$ Decays

preprint2007arXivOpen access

Precision determination of the CKM angle $γ/ϕ_3$ depends upon constraints on charm mixing amplitudes, measurements of doubly-Cabibbo suppressed amplitudes and relative phases, and studies of charm Dalitz plots tagged by flavor or CP eigenstates. In this note we describe the technique used at CLEO-c to constrain the $K_{S,L}ππ$ model uncertainty, and its impact on $γ/ϕ_3$ measurements at B-factories presented at the Charm 2007 Workshop.
