Measurement of the Strong Phase Delta (Kaon Pion) Through the Decay of Quantum-Correlated Neutral D-Anti-D Meson Pairs

We exploit quantum correlations in coherent D 0D0 pairs produced at the psi(3770) resonance to measure the strong phase difference deltaKpi between D0 → K+pi- and D 0 → K-pi+ decays. Using 818 pb-1 of e+e- collisions collected by the CLEO-c detector, we report a measurement of deltaKpi extracted from a Dalitz plot fit of KSpi+pi- in the joint decay D0,D0 → K+/-pi∓, KSpi +pi-. We find a preliminary result of deltaKpi = (32.1 +/- 21.6 +/- 12)°, where the first error is statistical and the second is systematic.
