SMEFT predictions for $gg\to hh$ at full NLO QCD and truncation uncertainties (2204.13045v3)
Published 27 Apr 2022 in hep-ph
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 $1/\Lambda$ 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 $\sqrt{s}=13$ TeV. The NLO corrections are implemented in the generator $\texttt{ggHH_SMEFT}$ in the $\texttt{Powheg-Box-V2}$ framework.
