Description
The Higgs physics program at the LHC has been up to now a big success crowned by the discovery of a 125 GeV Higgs boson in 2012. Theoretical predictions including higer order corrections were of paramount importance for the experimental collaborations in the analysis of the data leading to the discovery and are still essential to unravel the true nature of the new boson: is it a Standard Model (SM) Higgs boson or the first window to new physics and in particular to supersymmetry? In view of a Higgs physics precision program at the LHC at 14 TeV I will present two selected examples of such calculations: in a first part the cross section for the production of a SM Higgs boson in association with two gauge bosons at NLO QCD accuracy and matched with parton shower, in a second part the complete next-to-leading order calculation of the Higgs decays in a stop pair in the Next-to-Minimal Supersymmetric SM.
