Soft Gluon Radiation in Hadronic $t\bar{t}$ Production

Abstract

We investigate soft gluon radiation in hadronic $t\bar{t}$ production. By taking the top quark decay properly into account, we are able to study the interplay of radiation both before and after the decay of the top quarks. The production--decay and decay--decay radiative interferences depend sensitively on the relative size of the gluon energy and the decay width. Radiation patterns for various production mechanisms are compared.
