Decoupling of Anomalous Top-Quark-Decay Vertices in Angular Distribution of Secondary Particles
Bohdan Grzadkowski, Zenro Hioki
Abstract
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.
