Description
Higgs pair production offers the opportunity to probe correlations among the couplings of one or two Higgs bosons to fermions and gauge bosons. In this context, it serves as a powerful test of the underlying EFT framework. In this talk, we study Higgs pair production via gluon fusion within the Higgs Effective Field Theory (HEFT) including NLO and NNLO operators. Furthermore, we complement this study by a discussion of the process in the Standard Model Effective Field Theory (SMEFT) up dimension-8 and discuss the associated phenomenology.
