Decoupling of Anomalous Top-Quark-Decay Vertices in Angular Distribution of Secondary Particles
Angular distribution of a secondary particle from top-quark decays is studied in a simple and general manner, paying careful attention to how relevant the topquark production mechanism is. The conditions that lead to the distribution free from any possible anomalous top-quark decay interactions are specified. Some approximations adopted in earlier papers are relaxed and their relevance is discu...
متن کاملDecoupling of Anomalous Top-Decay Vertices in Angular Distribution of Secondary Particles
Angular distribution of a secondary particle from top-quark decays is studied in a simple and general manner, paying careful attention to how relevant the top-quark production mechanism is. The conditions that lead to the distribution free from any possible anomalous top-quark decay interactions are specified. It is discussed how important the approximations adopted in earlier papers are. PACS:...
متن کاملAngular Distribution of Leptons from Top-Quark Decays
Angular distribution of the secondary lepton in top-quark production followed by subsequent semi-leptonic decay is studied assuming general top-quark couplings. It is shown that the distribution does not depend on any possible anomalous tbW couplings and is determined only by the standard V −A decay vertex for any production mechanism if certain well-justified conditions are satisfied. PACS: 13...
متن کاملStudy of Top-quark Production and Decay Vertices with LCD Fast Simulation
We report a study of top-quark reconstruction in ee → tt̄ events at a 500 GeV linear collider using the LCD Fast simulator. The initial study of top-quark anomalous couplings is also reported. The final states of 4 jets and lepton as well as 6 jets are used. Using the 4 jets and lepton final state, we estimate the preliminary sensitivities for form factors at the γ/Ztt̄ vertex. In the 6 jets reco...
متن کاملMeasurements of top quark decay properties
I report on measurements of the properties of the top quark using data collected by the CDF and DØ detectors during Run II of the Fermilab Tevatron. The helicity of the W boson arising from top quark decay, the top quark decay branching ratios, and the top quark charge have all been measured, and the results in all cases are consistent with standard model expectations.
