DESY Theory SeminarHigher order corrections to $gg \to HH$
Kay Schönwald (Universität Zürich)
Double Higgs production is an important signature to determine the Higgs self-interaction experimentally and consequently establish if the electroweak symmetry is broken as predicted by the Standard Model. In this talk, I will present analytic methods which allow to approximate the NLO QCD corrections over the fullphase space and first steps at extending these techniques to NNLO and to mixed QCD-electroweak corrections at NLO. For the latter I also show results in the large top mass approximation which we computed recently.
