Abstract

We consider hadronic CP violation induced by chromoelectric dipole moments (CEDMs) of light quarks and the QCD theta parameter (θ). We concentrate on the strange quark CEDM especially in this paper. Using effective CP violating nucleon interactions induced by the CEDMs and θ with the SU(3) chiral Lagrangian technique, we calculate the EDMs for the ¹⁹⁹Hg atom, neutron, and deuteron. We also discuss supersymmetric (SUSY) contributions to the electric dipole moments with the mass insertion approximations and give constraints on the CP phases of the flavor changing SUSY breaking terms.
