The Standard Model Effective Field Theory (SMEFT) provides a consistent framework for comparing precision measurements at the LHC to the Standard Model. The observation of statistically significant non-zero SMEFT coefficients would correspond to physics beyond the Standard Model (BSM) of some sort. A more difficult question to answer is what, if any, detailed information about the nature of the underlying high scale model can be obtained from these measurements. In this work, we consider the patterns of SMEFT operators present in five example models and discuss the assumptions inherent in using global fits to make BSM conclusions. We find that including renormalization group effects has a significant impact on the interpretation of the results. As a by-product of our study, we present an up-dated global fit to SMEFT coefficients in the Warsaw basis including some next-to-leading order QCD corrections in the SMEFT theory.

  1. A HEFT Perspective on the Type-II Seesaw Model and the Complete Basis of Lepton-Number-Violating Operators

    hep-ph 2026-07 accept novelty 8.0 of 10

    First complete tree-level HEFT matching of the type-II seesaw and a Hilbert-series-checked, flavor-complete basis of lepton-number-violating HEFT operators through O(p^4).

  2. General form of effective operators from hidden sectors

    hep-ph 2024-12 accept novelty 7.0 of 10

    Hidden sectors coupled through the Higgs, neutrino, or hypercharge portal always generate a fixed set of dimension-six SMEFT operators, with signs fixed by causality and unitarity when the UV scaling is mild.

  3. Efficient on-shell matching

    hep-ph 2024-11 conditional novelty 7.0 of 10

    A numerical on-shell matching algorithm uses rational kinematics to compute EFT Wilson coefficients directly in a physical basis, including evanescent shifts.

  4. Renormalisation group evolution effects on global SMEFT analyses

    hep-ph 2024-12 conditional novelty 6.0 of 10

    Including RGE effects in a global SMEFT fit improves bounds on poorly constrained four-quark operators but weakens limits on modified Z q qbar couplings by up to a factor of ten.

  5. A Non-linear Representation of General Scalar Extensions of the Standard Model for HEFT Matching

    hep-ph 2024-11 conditional novelty 6.0 of 10

    The paper constructs a non-linear 'U representation' that separates Goldstone bosons from heavy scalars, enabling straightforward tree-level HEFT matching for general scalar extensions and giving explicit formulas for...

    hep-ph 2025-05 conditional novelty 5.0 of 10

    A new Mathematica package, mosca, automates tree-level on-shell matching to transform between operator bases and reduce Green's bases to physical bases in EFTs.
