Descripción
I will present projections for the sensitivity of near-term electron-positron colliders, FCC-ee, LEP3,
and the Linear Collider Facility, to new physics through precision measurements of Standard
Model interactions. These projections are interpreted within three complementary frameworks of
increasing generality: Higgs coupling modifiers, effective Higgs and electroweak couplings, and
global SMEFT fits incorporating renormalisation-group evolution, linear and quadratic EFT contributions,
and NLO corrections where available. Matching the EFT description to UV-complete
models, I will show how these results translate into projected sensitivities to representative newphysics
scenarios, including composite Higgs models and single-particle extensions of the SM. The
talk will also introduce the accompanying public release of an updated SMEFiT framework, allowing
the community to reproduce, extend, and adapt these results.
