Soft Gluon Radiation in Top Events: Effect of Hadronic $W$ Decays

Abstract

In reconstructing the top quark momentum from its decay products, one must account for extra jets that can result from radiation of gluons. In this paper we study soft gluon radiation in top production and decay at the Fermilab Tevatron. We consider the cases where one or both $W$ bosons decays hadronically, {\it i.e.}, where at least one of the top quarks can be fully reconstructed. We show results for gluon distributions at the Tevatron and find that radiation from the $W$ decay products contributes substantially in the central region.
