SM higgs production and decay at the LHC

The recent discovery of the Higgs boson at the LHC marked the completion of the Standard Model of strong and electroweak interactions. I will summarize the theoretical ingredients involved in the production and decay processes at the LHC that allowed for a quite concise picture of the properties of the discovered resonance. These theoretical calculations are a crucial contribution to the discrimination of the SM from BSM scenarios at the LHC, too.
