Description
We present the calculation of the contributions 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 NLO QCD corrections. The four-quark operators enter at two loops in this process and require the choice of a scheme to continue $\gamma_5$ to D dimensions. We report about new findings related to the interplay between different operators and illustrate the impact on Higgs phenomenology.
