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.

Interference effects in gluon-fusion Higgs boson production
Higher-order perturbative calculations find destructive signal-background interference in gg to H to gamma gamma and Z gamma, lowering the resonant production rate by approximately 1.6% and 3%.
