Three-loop mixed QCD-electroweak corrections to Higgs boson gluon fusion

Abstract

We compute the contribution of three-loop mixed QCD-electroweak corrections (${\alpha }_S^2{\alpha }^2$) to the $gg\to H$ scattering amplitude. We employ the method of differential equations to compute the relevant integrals and express them in terms of Goncharov polylogarithms.
