Gluon Radiation in Top Quark Production and Decay at $e^+e^-$ Colliders

High Energy Physics - Phenomenology 2011-07-19 v2

Abstract

We study gluon radiation in top quark production above threshold at high energy e+ee^+e^- colliders. We allow for the top quarks to be off-shell, considering radiation in both the top production and decay processes simultaneously. Our calculation includes all top width effects, spin correlations, and bb quark mass effects. We study the effects of gluon radiation on top mass reconstuction and examine the interference between production- and decay-stage radiation, which can be sensitive to the value of the top quark decay width.
