Description
We calculate the two-loop QCD corrections to Higgs boson pair production
in gluon fusion within Standard Model Effective Field Theory (SMEFT),
including also squared dimension-6 operators and double insertions of
operators. The different options to truncate the EFT expansion are
contrasted to a non-linear EFT approach (HEFT) and the effects are
illustrated with several phenomenological examples.
