“…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.

“…We here comment on the other contributions to d n from the Weinberg operator C W and the four-fermi interaction C f f . It has been known that the contribution from the charged Higgs boson exchange in two-loop diagrams to C W vanishes [20,43]. In addition, the contribution from the neutral Higgs boson exchanges to C W in two-loop diagrams and that to C f f in tree level diagrams vanish due to the hermicity of the Γ q ϕ matrices.…”

CP-Violating 2HDMs Emerging from 3-3-1 Models

We investigate CP violating 2 Higgs doublet models as an effective theory emerging from models with an SU (3) L ⊗ U (1) X gauge symmetry. Because of the extension of the electroweak symmetry, a characteristic structure of Yukawa interactions appears with new CP violating phases at the electroweak scale. In this scenario, the charged Higgs boson loop provides dominant and sizable contributions to the neutron electric dipole moment (nEDM) at one-loop level. We find that the prediction of the nEDM can be slightly smaller than the current upper limit, O(10 −26 ) e cm, with the mass of the charged Higgs boson and new CP violating phases to be a few hundred GeV and O(1), respectively, under the constraints from the B 0 -B0 mixing and the B → X s γ decay.

“…For models with multiple charged Higgs there is one contribution (and one parameter y k ) for each particle. A model with two charged Higgs is discussed in [11,12], with interesting earlier work highlighting the possible cancellation between the two charged Higgs contributions appearing in Refs. [48,49].…”

“…There are have been implementations of Type-Z in three-Higgs-doublet models (3HDM) using a Z 2 × Z 2 symmetry [11,12] or Z 3 [13,14]. For this work, we choose to use a Z 3 symmetric potential.…”

Type-Z models, where charged leptons, up type quarks and down type quarks each couple to a different scalar, are only possible when there are three or more Higgs doublets. We consider the Type-Z three Higgs doublet model imposed by a softly broken Z 3 symmetry. We take into account all theoretical and experimental constraints, highlighting the importance of perturbative unitarity and bounded from below conditions that we develop here, and which have a strong impact on B → X s γ. Since there can be cancellations between the two charged Higgs in B → X s γ (and in h → γγ), the lower bounds obtained on the charged Higgs masses are alleviated. We also discuss in detail the important physical differences between exact alignment and approximate alignment.
