6. Sensitivity to top-quark couplings in diboson production at lepton colliders

Eugenia Celada

We show results for the next-to-leading order electroweak corrections to $e^+e^− \to W^+W^−$ from dimension-six two-fermion top-quark operators in the SMEFT. We discuss the analytical computation and show results for future electron–positron colliders,focusing on the proposed LEP3 and FCC-ee that will operate at centre of mass energies below the $t\bar t$ production threshold. We compare the...
