Description

Experiments at future circular colliders such as the FCC-ee are expected to improve electroweak and top-quark physics in an unrivaled way. This talk gives an overview on the sensitivity of selected top-quark pair production observables taking into account dimension-six extensions of the Standard Model and following an optimal-observable analysis. Relevant observables and their parameterizations as function of the dimension-six operator strength are given.

Carrying out these generator-level studies to reconstructed objects in the FCC-ee environment requires for an adequate event selection and definition of the relevant objects of the process under study. Here, the semileptonic and dileptonic decay channels of tt¯ production are taken into account and recently improved methods for missing momentum component entanglement at lepton colliders are presented on reconstructed events.
