Angular Distribution of Leptons in General tt̄ Production and Decay
نویسنده
چکیده
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.

Signals of CP Violation in Distributions of tt̄ Decay Products at Linear Colliders
Angular and energy distributions for leptons and bottom quarks in the process ee → tt̄ → l/ (−) b · · · have been calculated assuming the most general top-quark couplings. The double distributions depend both on modification of the tt̄ production and (−) t → (−) b W decay vertices. However, the leptonic angular distribution turned out to be insensitive to non-standard parts of Wtb vertex. The met...

متن کاملAzimuthal angular dependence of decay lepton in e + e − → tt̄
We discuss top quark production and its subsequent decay for searching new physics at lepton colliders. The angular dependence of the decay leptons is calculated including both QCD corrections and anomalous γ/Z− tt̄ couplings. The off-diagonal spin basis for the top and anti-top quarks is shown to be useful to probe the anomalous couplings. TU-600 HUPD-0004 hep-ph/0008065 August 2000
متن کاملCP violating asymmetries of b quarks and leptons in e + e − → tt̄ and supersymmetry review
The distributions of the single decay b-quarks and leptons from e+e− → tt̄ assuming CP violation are reviewed. Different asymmetries , sensitive to independently to CP violation in the production and in the decay, and sensitive to the real and imaginary parts of d and d are defined. The analytic expressions are general and independent on the model of CP violation. In most of them all phase space...
