Schiff Moment of the Mercury Nucleus and the Proton Dipole Moment

We calculated the contribution of internal nucleon electric dipole moments to the Schiff moment of ${}^{199}\mathrm{H}\mathrm{g}$. The contribution of the proton electric dipole moment was obtained via core polarization effects that were treated in the framework of random phase approximation with effective residual forces. We derived a new upper bound $|d_p|<5.4\times {10}^{-24}e\mathrm{c}\mathrm{m}$ of the proton electric dipole moment.
