Top-beauty couplings at FCC-ee and synergies in global SMEFT interpretations — Kevin Kröninger¹, Romain Madar², Stéphane Monteil², and •Lars Röhrig^1,2 — ¹TU Dortmund University, Department of Physics — ²Université Clermont-Auvergne, Laboratoire de Physique de Clermont

Experiments for the post-LHC era as proposed nowadays are aimed at precision measurements in the electroweak, flavor, Higgs and top-quark sector. The FCC-ee among other proposals offers unrivaled precision in these fields and allows to combine measurements within the Standard Model Effective Field Theory at energy scales ranging from 91 GeV up to 365 GeV.

This talk motivates the combination of the top- and the Z→ bb energy scale and possible synergies through a common set of dimension-six operators. The estimation of several top-quark observable sensitivites is highlighted, as well as challenges and prospects of a full reconstruction in an FCC-ee environment. Systematically limited measurements of EWPO at the Z-pole at FCC-ee are discussed and novel hemisphere tagging techniques are presented to reduce these uncertainties.
