We present results for the next-to-leading order QCD corrections to the production and semi-leptonic decays of a top quark pair in hadron collisions, retaining all spin correlations. To evaluate the virtual corrections, we employ generalized D-dimensional unitarity. The computation is implemented in a numerical program which allows detailed studies of ttbar-related observables at the Tevatron and the LHC.

  1. Towards NNLO QCD predictions for off-shell top-quark pair production and decays

    hep-ph 2025-07 conditional novelty 8.0 of 10

    The first NNLO QCD prediction for off-shell W+W-bbbar production with massive bottom quarks at the LHC, using a double-pole approximation for the two-loop virtual and an on-shell matching for non-factorisable corrections.

  2. Double virtual QCD corrections to $t\bar{t}+$jet production at the LHC

    hep-ph 2025-11 unverdicted novelty 7.0 of 10

    Leading-colour two-loop virtual amplitudes for ttbar+jet are extracted analytically via finite-field evaluations and differential equations, then packaged in a C++ library with new numerical integration techniques.
