This book was released on 2008 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
