Description
The measured properties of the particle detected seven years ago at LHC at CERN indicate that it might be the Higgs boson of the Standard model. However, the theoretical and experimental uncertainties allow associations with extended models. Therefore it is of essential importance to investigate the properties of this particle in more detail. The determination of the Higgs potential is crucial to check whether this particle causes the electroweak symmetry breaking. The self-coupling strength has to be determined to measure the Higgs potential. This can be achieved by measuring the trilinear coupling in Higgs pair production. The dominant process of Higgs pair production is the loop induced gluon fusion via a top- and bottom quark loops. In this talk I will present the calculation of the NLO QCD corrections considering the complete top mass dependence in the scope of the Standard Model. Besides the uncertainties caused by the factorisation and renormalisation scale dependence, the uncertainties due to the choice of the top mass are considered. The results of the differential cross section as well as of the full hadronic cross section will be shown.
