Description
In this talk single and double Higgs boson production at the LHC are discussed. We introduce several approximation methods which at NLO are compared to exact results. Afterwards they are applied at higher orders to obtain real and virtual corrections to the production cross section. We also discuss two-loop correction to the process $gg\to ZZ$ induced by virtual top quark loops.
