摘要: We study the effects of QCD corrections to process {ital e}{sup +}{ital {minus}}{r_arrow}{ital t{bar t}}+{ital X}{r_arrow}{ital bW{sup +}{bar b}W{sup {minus}}}+{ital X} above threshold. show how treat consistently O}({alpha}{sub s}}) gluon radiation in both production and decay top quarks, while maintaining all angular correlations event. At this order there is an ambiguity event reconstruction whenever a real occurs final state. on quark mass helicity angle distributions. For 175 GeV collider energy 400 emitted predominantly quarks. {copyright} 1996 The American Physical Society.}
