Constraining the SMEFT at Present and Future Colliders
Abstract
We present results from SMEFiT3.0, a global SMEFT fit of Higgs, top quark, and diboson production data from the LHC. Our updated analysis includes recent inclusive and differential measurements from the LHC Run II, together with the exact implementation of electroweak precision observables (EWPOs) from LEP and SLD. We then analyse the impact of HL-LHC measurements by adding to SMEFiT3.0 the projections obtained by extrapolating from Run II data. Finally we estimate the potential of two proposed high-energy circular e+e- colliders, the FCC-ee and the CEPC, in further improving the bounds on the SMEFT parameters.
