Axial triangles in at two loops in QCD directly in four dimensions
Dario Kermanschah, Matilde Vicini
We numerically evaluate the two-loop QCD squared matrix element for in and with heavy top and bottom quarks circulating in a triangular fermion lo…
Heavy-quark box-loop corrections to at two loops in QCD
Dario Kermanschah, Matilde Vicini
We numerically compute the two-loop QCD corrections to production at the LHC mediated by light- and heavy-quark box loops. The calculation employs the pipeline of refs. arXiv…
Nf-contribution to the virtual correction for electroweak vector boson production at NNLO
Dario Kermanschah, Matilde Vicini
Multi-loop scattering amplitudes are difficult to evaluate due to singularities of the integrals involved, especially with increasing number of loops, external legs, and mass scale…
Two-loop QCD corrections for real and off-shell diphoton and triphoton production via quark loops
Dario Kermanschah, Matilde Vicini
We compute squared matrix elements at next-to-next-to-leading order in perturbative quantum chromodynamics for the production of two or three (on- or off-shell) photons mediated vi…
Numerical integration of the double- and triple-box integrals using threshold subtraction
Dario Kermanschah, Matilde Vicini
We numerically integrate finite two- and three-loop scalar integrals using the threshold subtraction method. This represents a first step towards extending our calculation of the $…
