• Future collider machines will be devoted to measure Standard Model (SM) parameters with high precision and further test the possibility of New Physics effects, appearing as possible deviations from the SM, which can be parametrized in a model-independent way through the Standard Model effective field theory (SMEFT). In order to meet the required precision, the calculation of higher order corrections is necessary both in the effective field theory expansion and in the SM limit. We present potential effects of Beyond the Standard Model physics in Higgs decays, by including all relevant dimension-six SMEFT operators at next-to-leading order accuracy in the electroweak and strong coupling and derive an indication of the sensitivity to Higgs anomalous couplings at the High Luminosity LHC and Future Circular electron-positron Collider.
