abstract

In this paper we present the complete expressions of the lepton and neutron electric dipole moments (EDMs) in the Standard Model Effective Field Theory (SMEFT), up to 1-loop and dimension-6 level and including both RG running contributions and finite corrections. The latter play a fundamental role in the cases of operators that do not renormalize the dipoles, but there are also classes of operators for which they provide an important fraction, $10-20\%$, of the total 1-loop contribution, if the new physics scale is around $\Lambda=5$ TeV. We present the full set of bounds on each individual Wilson coefficient contributing to the EDMs using both the current experimental constraints, as well as those from future experiments, which are expected to improve by at least an order of magnitude.

  1. A Guide to Functional Methods Beyond One-Loop Order

    hep-ph 2024-12 conditional novelty 7.0 of 10

    Functional methods are generalized to two-loop EFT matching and running with manifest gauge covariance, and the hard-region matching formula is proven to all loop orders.

  2. Neutrinoless Double-Beta Decays from Operator Mixing

    hep-ph 2026-08 conditional novelty 6.0 of 10

    Renormalization-group mixing lets heavy-quark dimension-seven operators feed neutrinoless double-beta decay, giving some of the strongest current bounds on these new-physics operators.

  3. New Physics contamination to precision luminosity measurements at future $e^+e^-$ colliders

    hep-ph 2025-01 conditional novelty 6.0 of 10

    Heavy new physics four-fermion operators can bias small-angle Bhabha luminosity calibration at future e+e- colliders at the level of the design precision, and luminosity-independent Bhabha asymmetries can constrain th...

  4. A common origin of the Higgs boson and the flavor hierarchies

    hep-ph 2024-12 conditional novelty 6.0 of 10

    A unified TeV-scale model produces the Higgs as a pseudo-Goldstone boson from the same gauge deconstruction that suppresses light-family Yukawa couplings and CKM mixing while leaving PMNS mixing anarchic.

    hep-ph 2026-01 conditional novelty 5.0 of 10

    In H→gg at a 240 GeV e+e− collider, the four-point energy-energy correlator with energy weight n=4 gives the strongest sensitivity to gluon spin correlations and, assuming perfect splitting-mode identification in the ...

  6. A tale of $Z$+jet: SMEFT effects and the Lam-Tung relation

    hep-ph 2024-12 conditional novelty 5.0 of 10

    Light-quark dipole operators cannot explain the observed violation of the Lam-Tung relation once SLC/LEP and LHC data are used to bound the Wilson coefficients.
