摘要：
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. Some approximations adopted in earlier papers are relaxed and their relevance is discussed. (C) 2003 Published by Elsevier Science B.V.
