Description
In the context of the European Strategy for Particle Physics 2026 Update, 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, CEPC, and LCF). We quantify the sensitivity of these colliders to the SMEFT parameter space in a global analysis, where we include renormalization group evolution effects and NLO corrections to the EFT cross-sections. We also assess the impact of different theory uncertainty scenarios. 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.
