abstract
Recent advances in $b$, $c$, and $s$ quark tagging coupled with novel statistical analysis techniques will allow future high energy and high statistics electron-positron colliders, such as the FCC-ee, to place phenomenologically relevant bounds on flavor violating Higgs and $Z$ decays to quarks. We assess the FCC-ee reach for $Z/h\to bs, cu$ decays as a function of jet tagging performance. We also update the SM predictions for the corresponding branching ratios, as well as the indirect constraints on the flavor violating Higgs and $Z$ couplings to quarks. Using type III two Higgs doublet model as an example of beyond the standard model physics, we show that the searches for $h\to bs, cu$ decays at FCC-ee can probe new parameter space not excluded by indirect searches. We also reinterpret the FCC-ee reach for $Z\to bs , cu$ in terms of the constraints on models with vectorlike quarks.

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...

Radiative generation of chiral vector operators in $b\to s \nu\bar{\nu}$ transition
Minimal one-loop models that generate both chiral vector operators for b→sνν̄ are systematically classified but cannot quantitatively explain the Belle II anomaly.

Counting b-jets at the FCC-ee as a probe of top-quark flavor physics
FCC-ee at 240 GeV can probe Λ_eff ∼ 7–13 TeV for scalar, vector and tensor eetu/eetc operators by counting b_P-odd single-b-jet multi-jet events.

Probing Lepton-Flavor-Violating Four-Lepton Operators at a Muon Collider
At a 3–14 TeV muon collider, projected sensitivity to lepton-flavour-violating four-lepton operators reaches C/Λ² ≈ (0.6–1.6)×10⁻¹¹ GeV⁻², beating current limits by 1–2 orders of magnitude and opening the currently un...

Beyond the Standard Model Higgs physics: Hunting $h \rightarrow bs$ with Higgs-strahlung at CEPC and FCC-ee
Under 2HDM-III parameters still allowed by Bs to mu+mu-, a BDT analysis projects 5 sigma sensitivity to h to bs at CEPC and FCC-ee with 1/ab of data.
