Abstract We calculate the three-loop matching coefficient C H H , required for a consistent description of Higgs boson pair production in gluon fusion through next-to-next-to-leading order QCD in the heavy top quark approximation. We also compute the g g → H H amplitude in m t → ∞ approximation in the full theory and show its consistency with an earlier computation in heavy-top effective theory.

- Top-quark mass effects in double and triple Higgs production in gluon-gluon fusion at NLO (2014, methodology): “ry involved. Computations including the exact top-quark mass dependence, i.e. in the Full Theory (FT), are only available at the leading order, and currently predictions at NLO [46] and NNLO accuracy [47,48] are obtained by means of approximations that build upon the Higgs-gluon effective field theory”

- Higgs Boson studies at future particle colliders (2019, methodology): “Gluon fusion production at a hadron collider has been computed within the SM at NNLO accuracy in the infinite top mass limit [58–61] and at NLO with the full top mass dependence [62–64], leading to a prediction whose theoretical and parametric uncertainties are of the order of a few percent.”
