Effective field theories of the Higgs boson not only allow for the sensible interpretation of Higgs coupling measurements, but also optimize the development of experimental analyses. Since the discovery of the Higgs, tremendous progress has been made in formulating suitable Higgs EFTs and exploring their properties. In this talk, I’ll highlight novel theoretical aspects of the prevailing Higgs EFT (the ``Standard Model EFT’') and their experimental implications for Higgs measurements at the LHC. I’ll then explore the limitations of this approach, presenting universal geometric criteria for determining the appropriate EFT for the Higgs sector and illustrating how LHC measurements can probe the geometry of electroweak symmetry breaking.
