High-precision calculation of the 4-loop QED contribution to the slope of the Dirac form factor
Stefano Laporta
We have evaluated with 1100 digits of precision the contribution of all the 891 mass-independent four-loop Feynman diagrams contributing to the slope of the Dirac form factor in QE…
Master integrals for the NNLO virtual corrections to scattering in QCD: the non-planar graphs
Stefano Di Vita, Thomas Gehrmann, Stefano Laporta +3
We complete the analytic evaluation of the master integrals for the two-loop non-planar box diagrams contributing to the top-pair production in the quark-initiated channel, at next…
Decomposition of Feynman Integrals on the Maximal Cut by Intersection Numbers
Hjalte Frellesvig, Federico Gasparotto, Stefano Laporta +4
We elaborate on the recent idea of a direct decomposition of Feynman integrals onto a basis of master integrals on maximal cuts using intersection numbers. We begin by showing an a…
