Query: 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
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.
