Query: Higgs Boson Pair Production at Next-to-Next-to-Leading Order in QCD   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 ${\cal
O}(20%)$ with respect to the next-to-leading order result at c.m. energy
$\sqrt{s_H}=14\,\text{TeV}$. 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 K factors as a
function of $s_H$.
