- Beschreibung
The development of a fully automated tool for the numerical calculation of NNLO corrections to scattering amplitudes is a highly desirable goal for the LHC era. In our approach, D-dimensional two-loop amplitudes are decomposed into Feynman integrals with four-dimensional numerators as well as (D-4)-dimensional remainders, which can contribute to the finite result through the interaction with the poles of Feynman integrals. The integrals with four-dimensional numerators are then expressed as tensor integrals in the loop momenta contracted with tensor coefficients. Hence, the calculation can be structured into the computation of the tensor coefficients, the treatment of (D-4)-dimensional numerator parts the reduction of the tensor integrals and the evaluation of the resulting master integrals.
