摘要

The future circular e+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 t-channel mediator, we analyse the synergy and interplay of future Tera-Z factories and non-collider tests conducted through direct and indirect searches of dark matter. Our results highlight the excellent prospect for a Tera-Z run to indirectly probe the presence and nature of dark matter.
