Query: Top quark electroweak couplings at future lepton colliders   We perform a comparative study of the reach of future $e^+e^-$ collider
options for the scale of non-resonant new physics effects in the top quark
sector, phrased in the language of higher-dimensional operators. Our focus is
on the electroweak top quark pair production process $e^+e^- \to Z^*/\gamma \to
t\bar t $, and we study benchmark scenarios at the ILC and CLIC. We find that
both are able to constrain mass scales up to the few TeV range in the most
sensitive cases, improving by orders of magnitude on the forecasted
capabilities of the LHC. We discuss the role played by observables such as
forward-backward asymmetries, and making use of different beam polarisation
settings, and highlight the possibility of lifting a degeneracy in the allowed
parameter space by combining top observables with precision $Z$-pole
measurements from LEP1.
