On the CP - odd Nucleon Potential

The CP-odd nucleon potential for different models of CP violation in the one meson exchange approximation is studied. It is shown that the main contribution is due to the π-meson exchange which leads to a simple one parameter CP-odd nucleon potential.

The Cp-odd Nucleon Interaction and the Value of T-violation in Nuclei

The relations between the value of Tand P-violating correlations in neutron scattering and different models of CP violation are discussed. It is shown that a specific structure of CP-odd nucleon interactions gives the possibility to obtain the essential information about CP-odd interaction at the quarkgluon level from nuclear experimental data. The up-to-date estimations for CP-violating nucleo...

CP-odd interaction of axion with matter

In the world with axion the precise measurement of gravitational force and check of the equivalence principle at small distances, λ ∼ 1cm and less, could provide an additional test of CP symmetry. Using the chiral approach, we connect the strength of CP-odd axion-nucleon vertex with CP-odd pion-nucleon coupling for color electric dipole moments of quarks as a low energy source of CP violation. ...

TPI-MINN-01-36 UMN-TH-2020-01 Best Values for the CP-odd Meson-Nucleon Couplings from Supersymmetry

In the supersymmetric models, the dominant sources of the hadronic flavor-diagonal CP violation at low energy are the theta term and the chromoelectric dipole moments of quarks. Using QCD sum rules, we estimate the preferred range and the best values for the CP-odd meson-nucleon coupling constants induced by these operators. When the theta term is removed by the axion mechanism, the size of the...

Renormalization of the P- and T-odd nuclear potentials by the strong interaction and enhancement of P-odd effective field.

Approximate analytical formulas for the self-consistent renormalization of P,T-odd and P-odd weak nuclear potentials by the residual nucleon-nucleon strong interaction are derived. The contact spin-flip nucleon-nucleon interaction reduces the constant of the P,T-odd potential 1.5 times for the proton and 1.8 times for the neutron. Renormalization of the P-odd potential is caused by the velocity...
