We calculate the electric-dipole and magnetic-quadrupole form factors of the deuteron that arise as a low-energy manifestation of parity and time-reversal violation in quark-gluon interactions of effective dimension four and six: the QCD vacuum angle, the quark electric and chromo-electric dipole moments, and the gluon chromo-electric dipole moment. Within the framework of two-flavor chiral perturbation theory, we show that the relative sizes of the corresponding moments allow an identification of the symmetry-breaking source.

Introduces an EFT framework relating paramagnetic molecular EDMs to nucleon EDMs, computes the required nuclear matrix elements for BaF via shell model, and derives limits on nucleon EDMs from existing data.
