Description

We present results from a global fit of dimension-six SMEFT operators that includes electroweak, Higgs-boson, top-quark, and flavor observables. The leading-order scale dependence of the SMEFT Wilson coefficients is consistently included in the evolution from the UV scale to the electroweak scale and the low-energy scale of flavor observables. In defining the SMEFT set of active operators we consider both the $U(3)^5$ and the $U(2)^5$-symmetric limits. The global fit is obtained within the HEPfit framework and is based on the state-of-the-art of both experimental results and theoretical predictions for all the observables considered.
