Abstract

We present a calculation of the NLO QCD corrections for Higgs-boson pair production in gluon fusion including effects of anomalous couplings within Standard Model Effective Field Theory (SMEFT). We study effects of different truncation options of the EFT expansion in 1/Λ and of double operator insertions, both at total cross-section level as well as for the distribution of the invariant mass of the Higgs-boson pair, at s = 13 TeV. The NLO corrections are implemented in the generator ggHH_SMEFT in the Powheg-Box-V2 framework.
