摘要
We exploit the quantum coherence between pair-produced D-0 and (D) over bar (0) in psi(3770) decays to make a first determination of the relative strong phase differences between D-0 -> K-S(0)pi(+)pi(-) and (D) over bar (0) -> K-S(0)pi(+)pi(-), which are of great importance in determining the Cabibbo-Kobayashi-Maskawa angle gamma/phi(3) in B- -> D-0((D) over bar (0))K- decays. Using 818 pb(-1) of e(+)e(-) collision data collected with the CLEO-c detector at E-cm 3.77 GeV, we employ a binned Dalitz-plot analysis of K-S(0)pi(+)pi(-) and K-L(0)pi(+)pi(-) decays recoiling against flavor-tagged, CP-tagged, and K-S(0)pi(+)pi(-)-tagged events to determine these strong phase differences.
