Title: New Physics Precisely at a Tera-Z Factory

Abstract: A future run on the Z-pole producing more than 1 trillion Z bosons (Tera-Z) such as proposed at FCC-ee will have indirect sensitivity to heavy new physics up to the tens of TeV scale via higher-order loop contributions to electroweak precision observables. I discuss how new physics with the right flavor structure to lie within reach of future colliders is well covered by loop-level probes at Tera-Z. These indirect quantum effects also provide complementary, or even better, sensitivity to potential deviations from the Standard Model that are typically thought to best be probed at energies above the Z-pole, e.g. Higgs couplings. A thorough Tera-Z program may thus anticipate aspects of the FCC program at higher energies and provide a wider scope of quantum exploration of the TeV scale than had previously been appreciated.
