Description
In the context of the European Strategy, we present projections for the new physics reach of future high-energy colliders using the latest version of the SMEFiT framework, with a focus on near-term electron-positron colliders (FCC-ee, LEP3 and LCF). We quantify their sensitivity to the SMEFT parameter space in a global analysis while accounting for renormalization group evolution effects and NLO corrections to the EFT cross-sections. We also assess the impact of different theory uncertainty scenarios, and consider a couple of representative UV models. The results of the global analysis are presented in terms of bounds on Wilson coefficients and effective couplings, providing a detailed picture of the potential of these colliders to probe physics beyond the Standard Model.
