NLO Yukawa and self-coupling corrections to gg→ HH — Gudrun Heinrich¹, Stephen Jones², Matthias Kerner¹, Thomas Stone², and •Augustin Vestner¹ — ¹KIT ITP, Karlsruhe, Germany — ²IPPP, Durham, United Kingdom

Higgs boson pair production is the prime process to constrain the trilinear Higgs boson self-coupling at the LHC, hereby testing whether the Higgs potential is Standard-Model-like. While full NLO QCD corrections to this process are available since some time already, calculations of NLO electroweak corrections have only emerged very recently and are not yet available in a public Monte Carlo program. Working towards this goal, we present the status of the calculation of the Yukawa-type and Higgs self-coupling corrections to Higgs boson pair production in gluon fusion.

Keywords: electro-weak corrections; Higgs Boson pair production; Higgs self-coupling
