Higgs boson production at hadron colliders in NNLO QCD Original Research Article

We compute the total cross-section for direct Higgs boson production in hadron collisions at NNLO in perturbative QCD. A new technique which allows us to perform an algorithmic evaluation of inclusive phase-space integrals is introduced, based on the Cutkosky rules, integration by parts and the differential equation method for computing master integrals. Finally, we discuss the numerical impact of the O(αs2) QCD corrections to the Higgs boson production cross-section at the LHC and the Tevatron.
