“…The constraining power of EDMs has stimulated a lot of different analyses in various UV completions of the SM. There are several studies of the electron and/or neutron EDMs in SUSY models [15][16][17][18], in Composite Higgs models [19][20][21], in Leptoquark models [22][23][24][25], in complex two-Higgs and three-Higgs doublet models [26][27][28][29][30] and in scotogenic models [31]. On the model independent side, [32] provides an analysis of the electron EDM including some contributions that arise at two-loop and at dimension-8 level, while [33] studies the neutron EDM in presence of an effective CP violating Higgs-gluon interaction encoded by a dimension-6 SMEFT operator and [34] analyzes the contribution to the neutron EDM induced by chromo-dipoles of second and third generation quarks.…”

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 Λ = 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.

“…Refs. [22][23][24][25] have explored models in this class. Note that if the model has a scalar leptoquark with appropriate charge assignment, the chirality flip can be picked up from a quark Yukawa coupling, e.g., the top Yukawa coupling.…”

We explore a model of dark matter (DM) that can explain the reported discrepancy in the muon anomalous magnetic moment and predict a large electric dipole moment (EDM) of the muon. The model contains a DM fermion and new scalars whose exclusive interactions with the muon radiatively generate the observed muon mass. Constraints from DM direct and indirect detection experiments as well as collider searches are safely evaded. The model parameter space that gives the observed DM abundance and explains the muon g – 2 anomaly leads to the muon EDM of dμ ≃ (4-5) × 10−22e cm that can be probed by the projected PSI muEDM experiment. Another viable parameter space even achieves $$ {d}_{\mu }=\mathcal{O}\left({10}^{-21}\right) $$ d μ = O 10 − 21 e cm reachable by the ongoing Fermilab Muon g − 2 experiment and the future J-PARC Muon g − 2/EDM experiment.

Electroweak baryogenesis can be driven by the top quark in a general two Higgs doublet model with extra Yukawa couplings. Higgs quartics provide the first order phase transition, while extra top Yukawa coupling ρtt can fuel the cosmic baryon asymmetry through the λtImρtt product, with flavor-changing ρtc coupling as backup. The impressive ACME 2018 bound on the electron electric dipole moment calls for an extra electron coupling ρee for exquisite cancellation among dangerous diagrams, broadening the baryogenesis solution space. The mechanism suggests that extra Yukawa couplings echo the hierarchical structure of standard Yukawa couplings. Phenomenological consequences in the Higgs search and flavor physics are discussed, with μ and τ EDM touched upon.
