Higgs production through gluon fusion: Updated cross sections at the Tevatron and the LHC

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 logarith...
