NLO corrections to top-quark pair hadroproduction in association with (heavy) bosons

Abstract content

We present the calculation, in a completely automated approach, of the NLO EW corrections to ttH, ttZ and ttW production at hadron colliders within the MadGraph5_aMC@NLO framework. We discuss also the impact of NLO QCD corrections on ttH, ttV and ttVV production with V=W, Z, gamma. Relevant distributions for the 13-TeV LHC are considered and inclusive results from 8 to 100 TeV are shown, also for the production of two top-quark pairs (tttt). NLO QCD (matched with parton shower) results, in a realistic experimental set-up for the LHC at 13 TeV, are provided for signal and background processes involved in the searches for ttH production with the Higgs boson decaying either into leptons or photons.
