Abstract We present updated predictions for the total cross section for Higgs boson production by gluon–gluon fusion in hadron collisions. Our calculation includes the most advanced theoretical information available at present for this observable: soft-gluon resummation up to next-to-next-to-leading logarithmic accuracy, the exact treatment of the bottom-quark contribution up to next-to-leading order, and two-loop electroweak effects. We adopt the most recent parametrization of parton distribution functions at next-to-next-to-leading order, and we evaluate the corresponding uncertainties. In comparison with our previous central predictions, at the Tevatron the difference ranges from +9% for m H = 115 GeV to −9% for m H = 200 GeV . At the LHC the cross section is instead significantly increased. The effect goes from +30% for m H = 115 GeV to +9% for m H = 300 GeV , and is mostly due to the new parton distribution functions. We also provide new predictions for the LHC at s = 10 TeV .
