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

Year: 2026

Type: article

Abstract: We present predictions for the production and decay of a top–antitop pair in association with a \rm 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.
