Abstract

The future circular e+ee^+e^- collider (FCC-ee or CEPC) will provide unprecedented sensitivity to indirect new physics signals emerging as small deviations from the Standard Model predictions in electroweak precision tests. Assuming new physics scenarios containing a dark matter candidate and a tt-channel mediator, we analyse the synergy and interplay of future Tera-ZZ factories and non-collider tests conducted through direct and indirect searches of dark matter. Our results highlight the excellent prospect for a Tera-ZZ run to indirectly probe the presence and nature of dark matter.
