Top Width Effects in Soft Gluon Radiation

Abstract

Soft gluons radiated in top quark production and decay can interfere in a way that is sensitive to the top width. We show how the width affects the gluon distribution in $e^{+}{e}^{-}\to t\bar{t}$ and discuss prospects for measuring $\Gamma$ from gluons radiated near threshold.
