One popular method to find new-physics effects is to use the Standard Model Effective Field Theory framework, which has the same symmetry and fields as of the Standard Model, but with higher-dimension operators included in the Lagrangian. In this talk, we use the measurements of Z-pole data at LEP to constrain Wilson coefficients of dimension-six operators involving gauge bosons and fermions. We consider the general case of flavour non-universal leptons and present constraints on the Wilson coefficients.
