Higgs boson pair production at next-to-next-to-leading order in QCD

Mostrar todas las versiones(2)

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...
