We compute the next-to-next-to-leading order QCD corrections for standard model Higgs
boson pair production inclusive cross section at hadron colliders within the large top-mass
approximation. We provide numerical results for the LHC, finding that the corrections are
large, resulting in an increase of O (20%) with respect to the next-to-leading order result at
cm energy s H= 14 TeV. We observe a substantial reduction in the scale dependence, with
overlap between the current and previous order prediction. All our results are normalized …

We compute the next-to-next-to-leading order QCD corrections for standard model Higgs boson pair production inclusive cross section at hadron colliders within the large top-mass approximation. We provide numerical results for the LHC, finding that the corrections are large, resulting in an increase of with respect to the next-to-leading order result at c.m. energy . We observe a substantial reduction in the scale dependence, with overlap between the current and previous order prediction. All our results are normalized using the full top- and bottom-mass dependence at leading order. We also provide analytical expressions for the factors as a function of .
