NLO QCD corrections to hadronic Higgs production with heavy quarks

The production of a Higgs boson in association with a pair of tt or bb quarks plays a very important role at both the Tevatron and the Large Hadron Collider. The theoretical prediction of the corresponding cross sections has been improved by including the complete next-to-leading order QCD corrections. After a brief description of the most relevant technical aspects of the calculation, we review the results obtained for both the Tevatron and the Large Hadron Collider.
