Jet activity in $$t\bar t$$ events and top mass reconstructions at hadron colliders. (English) Zbl 1003.81577
Summary: We analyze the impact of matrix-element corrections to top decays in HERWIG on several observables related the jet activity in $$t\overline t$$ events at the Tevatron and at the LHC. In particular, we study the effects induced by the higher-order corrections to top decays on the top mass reconstruction using the recently proposed $$J/\psi+ \ell$$ final states.
