Simulation of selected top-quark processes at the FCC-ee and their interpretation in terms of effective field theories — Cornelius Grunwald¹, Kevin Kröninger¹, Romain Madar², Stéphane Monteil², and •Lars Röhrig¹ — ¹Department of Physics, Dortmund, Germany — ²Laboratoire de Physique de Clermont, Clermont-Ferrand, France

While in the flavor-physics sector future upgrades of the LHCb detector at CERN and Belle II at KEK are aimed at precision measurements, experiments at future colliders such as the FCC-ee are expected to improve electroweak and top-quark physics in an unrivaled way. Since it is interesting to set the measurements by the FCC-ee into a global context, the estimation of the precision of selected top-quark processes is important for estimating the impact on the constraints of dimension-six operators.

In this talk, relevant observables and the impact of dimension-six operators on these observables are presented. The parameterizations as function of the dimension-six operator strength are given. This will allow to set constraints on the strength of dimension-six operators assuming uncertainties for the measurements at the FCC-ee.
