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.
