Description

We exploit the quantum coherence between pair-produced D0 and D0 in ψ(3770) decays to make a first determination of the relative strong phase differences between D0→KS0π+π- and D0→KS0π+π-, which are of great importance in determining the Cabibbo-Kobayashi-Maskawa angle γ/φ3 in B-→D0(D0)K- decays. Using 818 pb-1 of e+e- collision data collected with the CLEO-c detector at Ecm=3.77 GeV, we employ a binned Dalitz-plot analysis of KS0π+π- and KL0π+π- decays recoiling against flavor-tagged, CP-tagged, and KS0π+π--tagged events to determine these strong phase differences.
