Abstract
We present predictions for the inclusive cross section for Higgs boson production by gluon–gluon fusion in proton collisions at s=8 TeV. Our calculation is accurate up to next-to-next-to-leading order in QCD perturbation theory and includes soft-gluon effects up to next-to-next-to-leading logarithmic accuracy and two-loop electroweak corrections. The dependence on heavy-quark masses is taken into account exactly up to next-to-leading order and next-to-leading logarithmic accuracy, and a treatment of the Higgs boson line-shape is provided according to the complex-pole scheme.

With the LHC running at 8 TeV and expecting to deliver an integrated luminosity of O(15 fb−1) per experiment, the discovery or exclusion of the Standard Model (SM) Higgs boson can really be envisaged by the end of 2012
Summary
Other recent results for the Higgs production cross section at the LHC, obtained at different levels of theoretical accuracy, are presented in Refs. Since no exact results are available at NNLO accuracy, at this order we only include the top-quark contribution in the mt → ∞ limit by adding soft-gluon effects at NNLL, as in Refs.
