摘要:

        This presentation provides a phenomenological analysis of the production of tt ̅w and tt ̅wj in the context of the Standard Model at the LHC with a center-of-mass energy of √s = 13 TeV. The predictions are computed with the full off-shell effects included and in the narrow-width-approximation at NLO in QCD using the HELAC-NLO software package. The analysis is focused on investigating various aspects of the computation, such as the impact of employing different theoretical modeling approaches, cross section ratio σ_tt ̅w_+/σ_tt ̅w_− and the charge asymmetries. The predictions are presented and discussed at the integrated and differential fiducial levels.
