Résumé |
Two-loop scattering amplitudes are a vital component in high-precision
cross section calculations at the LHC. At higher multiplicities, the
increased number of scales can make the algebra of analytic amplitude
calculations intractable. In this talk, we discuss how to apply numerical
techniques to sidestep this intermediate complexity and combine them
with physical properties of the amplitude to efficiently determine its
analytic form. In particular we focus on planar five-point amplitudes in
QCD. |
