Hadronic production of ttZ in the POWHEG BOX framework


I will present a recent calculation of ttZ and ttll production at the LHC at NLO in QCD, which was matched to a parton shower using the POWHEG method. After introducing the process and the framework, I will talk about our implementation itself and about a study of the effects on final-state observables of off-shell contributions of the Z boson and spin-correlations in the decays of the top quarks, which are on the order of 10-20%.
