Query: Gluon Radiation and Top Quark Physics   Radiation of gluons gives rise to extra jets in top quark events that can
lead to complications in event reconstruction and mass measurement. I review
recent results for gluon radiation in top quark production and decay, and
discuss their implications for top quark physics.
