Precise SMEFT predictions for di-Higgs production

Abstract

We present results of precision calculations for di-Higgs production that combine NLO QCD corrections with operators at canonical dimension six within Standard Model Effective Field Theory (SMEFT). We discuss possible options for operator contributions within a given EFT framework and sources of theory uncertainties.
