Rational terms in two-loop calculations

Recently, we published the OpenLoops 2 program, a powerful tool for the automation of NLO QCD and NLO EW calculations for all relevant LHC processes with high numerical stability in hard regions as well as in soft and collinear regions. This not only allows for highly efficient and accurate NLO calculations, but also for the numerically stable computation of NNLO real-virtual contributions.
In this talk we present first steps towards the automation of the numerical calculation of two-loop amplitudes with four-dimensional numerators. The new methods and results presented in this talk are expected to be published shortly before the conference.
