摘要：
We present the state-of-the-art predictions for off-shell t (t) over barb (b) over bar production with di-lepton decays at the LHC with root s = 13 TeV. Results are accurate at NLO in QCD and include all resonant and non-resonant diagrams, interferences, and finite-width effects for top quarks and W bosons. We discuss the impact of QCD corrections and assess theoretical uncertainties from scale and PDF dependence at the integrated and differential level. Additionally, we investigate the size of contributions induced by initial-state b quarks to the NLO cross section.
