Scheming in the SMEFT. . . and a reparameterization invariance!
Abstract We explain a reparameterization invariance in the Standard Model Effective Field Theory present when considering ψ ¯ ψ → ψ ¯ ψ $$ \overline{\psi}\psi\ \to \overline{\psi}\psi $$ scatterings (with ψ a fermion) and how this leads to unconstrained combinations of Wilson coefficients in global...
