Impact on γφ3 from CLEO-c Using CP-tagged DS,Lππ Decays
Abstract
Precision determination of the CKM angle γ/φ3 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 KS,Lππ model uncertainty, and its impact on γ/φ3 measurements at B-factories presented at the Charm 2007 Workshop.
