Description
We demonstrate that the Feynman-Diagram gauge provides a transparent decomposition of SMEFT contributions according to scattering mechanisms and gauge-higgs interaction vertices, enabling a direct physical interpretation of Wilson-coefficient effects in electroweak scattering.
Building upon this framework, we perform feasibility studies for future TeV-scale lepton colliders (ILC, FCC-ee, Muon Colliders, etc), evaluate their sensitivity to the relevant SMEFT operators, and derive the projected bounds on the corresponding Wilson coefficients.
