Analytic form of planar two-loop five-patron scattering amplitudes in QCD
Résumé
We discuss the recent calculation of the analytic form of the two-loop five-parton amplitudes in QCD. These constitute the full set of amplitudes required for the computation of NNLO QCD corrections to three-jet production at hadron colliders in the leading-color approximation. The calculation is done by combining efficient numerical evaluations and analytic reconstruction techniques. The techniques we present open the door to the evaluation of multi-leg two-loop amplitudes beyond the current state of the art.
