Soft Jets and Top Mass Measurement at the Tevatron

Abstract

Extra soft jets in top events in $p\bar{p}$ collisions may arise not only from gluons radiated off initial state partons or final state $b$ quarks, but may also be radiated from the $t$ quarks themselves. We discuss predictions for distributions of soft gluons in $t\bar{t}$ production at the Tevatron and the implications for attempts to measure the top mass by reconstructing the invariant mass of its decay products.
