We study the effect of the ”chromo-electric” dipole moment on the electric dipole moment(EDM) of the neutron in the two Higgs doublet model. We systematically investigate the Weinberg’s operator O3g = GG ˜ G and the operator Oqg = qσ ˜ Gq, in the cases of tan β ≫ 1, tan β ≪ 1 and tan β ≃ 1. It is shown that Osg gives the main contribution to the neutron EDM compared to the other operators, and also that the contributions of Oug and O3g cancel out each other. It is pointed out that the inclusion… 

Weinberg operator contribution to the nucleon electric dipole moment in the quark model

We evaluate the contribution of the CP violating gluon chromo-electric dipole moment (the so-called Weinberg operator, denoted as $w$) to the electric dipole moment (EDM) of nucleons in the

Analysis of the Phase Structure in Extended Higgs Models

We study the generation of the baryon asymmetry in the context of electroweak baryogenesis in two different extensions of the Standard Model. First, we consider an effective theory, in which the

Baryogenesis in the Two-Higgs Doublet Model

We consider the generation of the baryon asymmetry in the two-Higgs doublet model. Investigating the thermal potential in the presence of CP violation, as relevant for baryogenesis, we find a strong

Nuclear electric dipole moment of light nuclei in the gaussian expansion method

The nuclear electric dipole moment is a very sensitive probe of CP violation beyond the standard model, and for light nuclei, it can be evaluated accurately using few-body calculational methods. In

CP Violation From Standard Model to Strings

A review of CP violation from the standard model to strings is given which includes a broad landscape of particle physics models, encompassing the nonsupersymmetric four-dimensional (4D) extensions

Contribution of the Weinberg-type operator to atomic and nuclear electric dipole moments

Abstract The contribution of the CP violating three-gluon Weinberg operator, $$ \frac{1}{3!}w{f}^{abc}{\epsilon}^{\nu \rho \alpha \beta}{G}_{\mu \nu}^a{G}_{\alpha \beta}^b{G}_{\rho}^{c\mu} $$ 1

CP-violating phenomenology of flavor conserving two Higgs doublet models

We analyze the constraints on CP-violating, flavor conserving two Higgs doublet models implied by measurements of Higgs boson properties at the Large Hadron Collider (LHC) and by the nonobservation

It is shown that, in models in which neutral-Higgs-boson exchange mediates {ital CP} violation, {ital T} and {ital P} odd electron-nucleon interactions would arise at a measurable level. In

CP Violation in the Renormalizable Theory of Weak Interaction

In a framework of the renormalizable theory of weak interaction, problems of CP-violation are studied. It is concluded that no realistic models of CP-violation exist in the quartet scheme without

Chromoelectric dipole moments of heavy quarks and purely gluonic CP violating operators.

The induced gluonic operators of dimension 8 may be the dominant mechanism for generating the neutron electric dipole moment.
