Complete NLO QCD plus EW corrections are calculated for off-shell ttbar production in the lepton-plus-jets channel, including all doubly, singly and non-resonant diagrams with their interferences.
A data-driven ddFONLL extrapolation method accounts for LHC-observed charm fragmentation non-universality to derive higher total charm cross sections from D0 fiducial measurements at 5 and 13 TeV, consistent with NNLO QCD predictions.
Near-threshold top-quark pair production cross section at 13 TeV LHC is 11.67 pb with +1.43/-1.47 pb uncertainty, including NRQCD Green's function effects and comparison to POWHEG-BOX.
The report reviews progress since 2021 in fixed-order computations for LHC applications and identifies processes requiring missing higher-order corrections to match anticipated experimental precision.
