Planar Six-Point Feynman Integrals for Four-Dimensional Gauge Theories
Samuel Abreu, Pier Francesco Monni, Ben Page +1
We compute all planar two-loop six-point Feynman integrals entering scattering observables in massless gauge theories such as QCD. A central result of this paper is the formulation…

Four-loop two-mass tadpoles and the parameter
Samuel Abreu, Arnd Behring, Andrew McLeod +1
We calculate four-loop QCD corrections to the electroweak parameter with a non-vanishing quark mass. At three loops, it was observed that elliptic integrals contribute to t…
