Description
We present constraints on dimension-6 Standard Model Effective Field Theory (SMEFT) operators from a global fit to electroweak, Drell-Yan, Higgs-boson, top-quark, and flavour observables. The analysis is performed under different flavour symmetry assumptions, including $U(3)^5$ and $U(2)^5$, and considers both global and single-coefficient fits. The scale dependence of the Wilson coefficients is consistently included via renormalization group evolution from the ultraviolet to low-energy scales. We discuss the complementarity of observables, highlighting the growing impact of Higgs precision measurements in probing New Physics.
