Query: P- and T-Violating Lagrangians in Chiral Effective Field Theory and
  Nuclear Electric Dipole Moments   A scheme to derive hadronic interactions induced by effective multi-quark
terms is presented within the framework of chiral effective field theory. It is
employed to work out the list of parity- and time-reversal-symmetry-violating
hadronic interactions that are relevant for the computation of nuclear
contributions to the electric dipole moments of the hydrogen-2, helium-3 and
hydrogen-3 nuclei. We also derive the scattering and Faddeev equations required
to compute electromagnetic form factors in general and electric dipole moments
in particular.
