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.

This thesis presents a Dalitz plot analysis of D0 to K0S PI0 PI0 using the CLEO-c data set of 818 inverse picobarns of positron-electron collisions accumulated at center-of-mass energy 3.77 GeV. This corresponds to about 3 million D0-anti-D0 pairs from which we select 1260 tagged candidates with a background of roughly 6%. We find that S-wave features dominate the PI0 PI0 axis of the Dalitz plot, contributing about one-third of the total decay rate, while the K*(892) is the dominant K0S PI0 contribution. Using three tag modes and correcting for quantum correlations we determine that the D0 to K0S PI0 PI0 branching ratio is 1.059% with a statistical uncertainty of 0.049% and a systematic uncertainty of 0.050%.

This first open access volume of the handbook series contains articles on the standard model of particle physics, both from the theoretical and experimental perspective. It also covers related topics, such as heavy-ion physics, neutrino physics and searches for new physics beyond the standard model. A joint CERN-Springer initiative, the "Particle Physics Reference Library" provides revised and updated contributions based on previously published material in the well-known Landolt-Boernstein series on particle physics, accelerators and detectors (volumes 21A, B1,B2,C), which took stock of the field approximately one decade ago. Central to this new initiative is publication under full open access
