abstract
In this paper we present the complete one-loop matching conditions, up to dimension-six operators of the Standard Model effective field theory, resulting by integrating out the two scalar leptoquarks $S_{1}$ and $S_{3}$. This allows a phenomenological study of low-energy constraints on this model at one-loop accuracy, which will be the focus of a subsequent work. Furthermore, it provides a rich comparison for functional and computational methods for one-loop matching, that are being developed. As a corollary result, we derive a complete set of dimension-six operators independent under integration by parts, but not under equations of motions, called Green's basis, as well as the complete reduction formulae from this set to the Warsaw basis.

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...

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.

Complete two-loop Yukawa-induced running of the Higgs-gluon coupling in SMEFT
For the first time, the two-loop Yukawa-induced renormalisation-group running of the Higgs-gluon coupling from D^2H^4 and D H^2 ψ^2 SMEFT operators is computed.

Connecting $t$-channel Dark Matter Models to the Standard Model Effective Field Theory
One-loop SMEFT Wilson coefficients for leptophilic t-channel dark matter, combined with global fits, exclude large coupling regions, especially C_ell_ell for doublet mediators and C_ed above 3 TeV.

Electroweak Scalar Effects Beyond Dimension-6 in SMEFT
One-loop dimension-eight SMEFT matching is derived for complex triplet and two-Higgs-doublet scalar extensions, and the dimension-eight terms are shown to matter for GigaZ electroweak precision projections.

Constraints on lepton-flavor mixing with third-generation new physics
The U(2)_ℓ-breaking spurion δ is constrained to |δ| < 0.051 (95% CL) by R_K(*) and B_s→μμ data, with derived upper limits for LFV τ and B decays.
