Sumario:Effective field theories provide an elegant approach to study possible new physics scenarios, by comparing precision measurements with Standard Model predictions. The latest results on multi-boson processes from the ATLAS and CMS collaborations at the LHC, which are sensitive to anomalous gauge couplings and thus can be used to constrain EFT operators, will be presented. The consistency of the Standard Model can also be tested by a global electroweak fit to precision observables in the electroweak sector. We will present here the precision measurement of the W boson mass as well as the new results on the determination of the electroweak mixing angle and the top quark mass.
