Hadronic electric dipole moments induced by strangeness and constraints on supersymmetricCPphases

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.
