Description

I will present next-to-next-to-leading-order (NNLO) QCD predictions for top-quark pair production in association with a jet at the LHC. I will first describe the computation of the two-loop scattering amplitudes in the leading-colour approximation and discuss the impact of the higher-order corrections on the total cross section and selected differential distributions.
