QCD Radiation in Top Quark Pairs

We characterize additional jet activity in top quark pair production at hadron

colliders. The goal is development of tools that can correctly describe these

events in data, both as an aid to studying the top quark, and to better

understand top as a background for new physics searches. We show that while

top pair production is truly a multiscale problem, making a leading-order

description difficult, such events will provide an excellent arena for

studying generic features of QCD already at Run II of the Tevatron.
