Predictions for off-shell $t\bar{t}Z$ production at the LHC: the complete set of LO and NLO contributions

We present predictions for the production and decay of a top–antitop pair in association with a Z boson in the multi-lepton decay channel at the LHC. Our results include the complete set of LO and NLO contributions. Since our calculation is based on full matrix elements, off-shell effects are entirely taken into account. Integrated and differential cross-sections are reported for a realistic fiducial setup.
