Combining chromomagnetic and four-fermion operators with leading SMEFT operators for gg hh at NLO QCD
Abstract
We present the calculation of the contribtuions from the chromomagnetic and four-top-quark-operators within Standard Model Effective Field Theory (SMEFT) to Higgs boson pair production in gluon fusion, combined with full NLO QCD corrections. We study the effects of these operators on the total cross section and the invariant mass distribution of the Higgs-boson pair, at s=13.6 TeV. These subleading operators are implemented in the generator ggHHSMEFT, in the same Powheg-Box-V2 framework as the leading operators, such that their effects can be easily studied in a unified setup.
