A complete one-loop matching calculation for real singlet scalar extensions of the Standard Model to the Standard Model effective field theory (SMEFT) of dimension-six operators is presented. We compare our analytic results obtained by using Feynman diagrams to the expressions derived in the literature by a combination of the universal one-loop effective action (UOLEA) approach and Feynman calculus. After identifying contributions that have been overlooked in the existing calculations, we find that the pure diagrammatic approach and the mixed method lead to identical results. We highlight some of the subtleties involved in computing one-loop matching corrections in SMEFT.

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.

Accuracy complements energy: electroweak precision tests at Tera-Z
Z-pole precision at a Tera-Z factory gives projected sensitivities to Higgs and gauge SMEFT operators that are competitive with, and complementary to, higher-energy runs such as WW and ZH.
