Description
We present state-of-the-art, high-precision predictions for top-quark pair production in the di-lepton channel at the LHC.
Our results are based on the narrow-width approximation and include approximate NNLO corrections in the production subprocess, exact NNLO corrections in the decay sub-process as well as exact NLO-production/NLO-decay interferences.
We will briefly outline the structure of this new calculation and discuss the importance of the corrections beyond NLO.
A comparison of these improved predictions to ATLAS and CMS fiducial-region measurements will also be shown.
