Description

In the past few years, remarkable progresses in multi-loop calculations have opened the doors to the computation of massless two-loop five-point scattering amplitudes, allowing to complete NNLO QCD predictions for complicated $2 \rightarrow 3$ processes like tri-photon, tri-jet and di-photon plus jet production. Very recently, also the two-loop five-point scattering amplitudes with one external massive leg have been made available in literature.
Due to these successful progresses in multi-loop computations, it is reasonable thinking that also two-loop amplitudes with several massive legs will be accessible in the next future, allowing to complete NNLO QCD computations for processes with massive final-state particles.
In this talk we will discuss about recent progresses in NNLO QCD computations for processes where a heavy-quark pair is produced in association with a massive boson.
