Abstract
We calculate for the first time the electric dipole moment (EDM) of the nucleus within the three-body cluster model using the Gaussian expansion method, assuming the one-meson exchange , CP-odd nuclear forces. It is found that the EDM of is 2 times more sensitive to the isovector pion exchange , CP-odd nuclear force than the deuteron EDM because of the CP-odd interaction between the nucleons and the cluster. The EDM is also calculated in the same framework as an three-body system. We also test the ab initio calculation of the EDM of the deuteron, , and nuclei using the realistic Argonne nuclear force. In the ab initio calculations, good agreements with previous studies are obtained. We finally discuss the prospects for new physics beyond the standard model.
