Abstract

In this section, we discuss the calculation of a key component in making such predictions— the loop amplitude. Specifically, we discuss the computation of an independent set of analytical two-loop five-gluon helicity amplitudes in the leading-colour approximation. These amplitudes are an ingredient for the phenomenologically relevant description of three-jet production at next- to-next-to-leading order (NNLO) for hadron colliders. Nonetheless, the methods we present are completely general and can also be applied to predictions for electron–positron collisions.
