Descripción
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 mH = 115   GeV to -9% for mH = 200   GeV. At the LHC the cross section is instead significantly increased. The effect goes from +30% for mH = 115   GeV to +9% for mH = 300   GeV, and is mostly due to the new parton distribution functions. We also provide new predictions for the LHC at sqrt(s) = 10   TeV. © 2009 Elsevier B.V.
