abstract
A Tera-$Z$ factory, such as FCC-ee or CEPC, will have indirect sensitivity to heavy new physics up to the tens of TeV scale through higher-order loop contributions to precision measurements at the $Z$ pole. These indirect quantum effects may provide complementary, or even better, sensitivity to potential deviations from the Standard Model that are typically thought to best be constrained at leading order at higher energies above the $Z$ pole. We show in the SMEFT framework how accuracy complements energy for operators that modify the Higgs and gauge boson two- and three-point functions, leading to improved projected sensitivities for models such as the real singlet scalar, weakly interacting massive particles, and a custodial weak quadruplet. A thorough Tera-$Z$ programme may thus anticipate aspects of physics runs at higher energies and provide a wider scope of quantum exploration of the TeV scale than had previously been appreciated.

The Dark Side of a Tera-Z Factory
Future Tera-Z runs at FCC-ee/CEPC could indirectly probe TeV-scale t-channel dark matter portals through one-loop and two-loop electroweak precision shifts, and in leptophilic models would be the only planned experime...

Descoped and Upscoped FCC-ee Running Scenarios in the SMEFT
A descoped FCC-ee retains most of its SMEFT reach if a reduced-luminosity top-quark run is kept, while upscoped luminosity increases barely improve the global fit.

Could electron-top interactions spoil the measurement of the Higgs trilinear? -A quantitative estimate at future lepton colliders-
Electron-top four-fermion operators are constrained by FCC-ee fermion-pair measurements strongly enough that they do not spoil the ~17% one-sigma extraction of the Higgs trilinear coupling.

Search for new physics effects in $\nu\bar{\nu}\gamma$ production at a Tera-Z factory
A cut-based analysis of e+e−→ννγ at a Tera-Z factory is projected to constrain BR(Z→ννγ) to about 2×10^-9 (3σ, no systematics), an order-3 improvement over LEP but above the SM value 7.2×10^-10.

Cornering Natural SUSY at a Tera-$Z$ Factory
FCC-ee's Tera-Z electroweak precision program could probe natural supersymmetric particles up to multi-TeV masses, sometimes better than Higgs coupling measurements, assuming Standard Model theory uncertainties can be...
