Abstract

We present the first fully differential predictions for the production cross section of a Higgs boson via the gluon fusion mechanism at next-to-next-to-next-to-leading order ( N 3 LO ) in QCD perturbation theory. Differential distributions are shown for the two-photon final state produced by the decay of the Higgs boson for a realistic set of fiducial cuts. The N 3 LO corrections exhibit complex features and are in part larger than the inclusive N 3 LO corrections to the production cross section. Overall, we observe that the inclusion of the N 3 LO QCD corrections significantly reduces the perturbative uncertainties and leads to a stabilization of the perturbative expansion.
