Numerical integration of the double- and triple-box integrals using threshold subtraction

Year: 2024

Type: conference-paper

Abstract: We numerically integrate finite two- and three-loop scalar integrals using the threshold subtraction method. This represents a first step towards extending our recent calculation of the $N_f$-part to the full NNLO virtual corrections for the production of massive vector bosons.
