Nuclear electric dipole moment of 3-body systems 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 the few-body calculational methods.In this work, we evaluate the electric dipole moment of 3-body nuclear systems using the Gaussian expansion method with the Av8 nuclear force, and assuming the one-meson exchange model for the P, CP-odd nuclear force.
