SOFT GLUON RADIATION IN TOP-QUARK EVENTS - EFFECT OF HADRONIC W DECAYS

In reconstructing the top quark momentum from its decay products, one must account for extra jets that can result from the radiation of gluo ns. In this paper we study soft gluon radiation in top quark productio n and decay at the Fermilab Tevatron. We consider the cases where one or both W bosons decay hadronically, i.e., where at least one of the t op quarks can be fully reconstructed. We show results for gluon distri butions at the Tevatron and find that radiation from the W decay produ cts contributes substantially in the central region.
