tWZ production at NLO in QCD in the SMEFT
Abstract
At NLO in QCD, the tWZ production process interferes with resonant LO processes, ttZ and tt, and a method to meaningfully disentangle these overlapping processes needs to be employed. I discuss the diagram-removal procedure needed to obtain an operative definition of tWZ at NLO accuracy. I also show the predictions we obtain in the context of the Standard Model and in the Standard Model Effective Field Theory including the relevant dimension-six SMEFT operators.
