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.
