Search for the Higgs Boson in H->WW Decays at the D0 Experiment and Precise Muon Tracking
… anti-proton collisions with data taken at the D0 experiment at the Tevatron collider. The data set was taken between April 2002 and September 2003 and has an integrated luminosity of approximately 147 pb^-1. An analysis of the di-muon decay channel of the W pairs was developed which can be …

Measurement of strange hadron production and perspectives for the search of D0→ μ+μ− decay at LHCb
… outlook of the search of the very rare D0→ μ+μ− decay is reported. This process involving flavour changing neutral currents is sensitive to contributions from different new physics scenarios. A selection for this decay and its possible background contributions are presented as obtained …

Analysis of Neutral D Meson Two-Body Decays to a Neutral Kaon and a Neutral Pion
… transitions, a decay rate asymmetry of D0 → K0S π0 compared to D0 → K0Lπ0 has been predicted to be non-zero. If New Physics interferes in doubly Cabibbo-suppressed D decays, the measurement of this asymmetry would differ from the predicted value and may provide evidence for CP-violation …

D(0) Decays From Electron-Positron Collisions: Precision, Rare and Substructure Results
Three analyses of D0 meson decays are presented which use the data collected with the CLEO II detector at the Cornell Electron Storage Ring. First, a precision measurement of the ratio of the D0 → K-pi +pi0 branching fraction to that of D 0 → K-pi+ is performed resulting in the best …

Analysis of the neutral D-meson decay to a neutral kaon and two neutral pions
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 …

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 …

For the unit testing of safety-critical software, this standard requires the testing process to meet a strong source code structure coverage criterion, referred to as Modified Condition/Decision Coverage criterion. This part of the …

Mixing and Doubly Cabibbo -Suppressed Decays of Neutral Charmed Mesons
"A study of the decay D0 → K+pi-pi+pi - is presented. This ""wrong-sign"" decay can proceed through either a doubly Cabibbo-suppressed decay or mixing to a D¯0 followed by the Cabibbo-favored (or ""right-sign"") decay D0 → K-pi+pi-pi +. The Cabibbo-favored decay is used as a …
