Virtual corrections to Higgs boson pair production in the large top quark mass limit

Virtual corrections to Higgs boson pair production in the large top quark mass limit

We calculate the three-loop matching coefficient CHH, 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 gg→HH amplitude in mt→∞ approximation in the full theory and...
