Chebyshev Approximations of Feynman Integrals for Collider Physics
Samuel Abreu, Afonso Guerreiro, Ben Page
We present a novel approach for solving canonical differential equations for Feynman integrals based on an approximation of the integrals with Chebyshev polynomials. By exploiting…
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…
A generalized picture of colour decoherence in dense QCD media
Samuel Abreu, Xoán Mayo López, Guilherme Milhano +1
We revisit the calculation of the soft gluon emission probability off a colour-singlet system that evolves in a quark-gluon plasma. The antenna is created in th…
Two-Loop Five-Point Two-Mass Planar Integrals and Double Lagrangian Insertions in a Wilson Loop
Samuel Abreu, Dmitry Chicherin, Vasily Sotnikov +1
We consider the complete set of planar two-loop five-point Feynman integrals with two off-shell external legs. These integrals are relevant, for instance, for the calculation of th…
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…
