Quark and gluon form factors in four-loop QCD

High Energy Physics - Phenomenology 2022-06-08 v1 High Energy Physics - Theory

Abstract

We compute the photon-quark and Higgs-gluon form factors to four-loop order within massless perturbative Quantum Chromodynamics. Our results constitute ready-to-use building blocks for N4{}^4LO cross sections for Drell-Yan processes and gluon-fusion Higgs boson production at the LHC. We present complete analytic expressions for both form factors and show several of the most complicated master integrals.
