Description
Paramagnetic molecules are increasingly powerful systems for probing CP-violating physics through electric dipole moment (EDM) measurements. Although usually interpreted in terms of the electron EDM, these systems also exhibit sensitivity to hadronic CP-violating sources. We present an effective field theory framework that connects molecular EDM observables to the EDMs of nucleons. Using power counting, we identify the leading contributions and determine the nuclear matrix elements required for this mapping. As an application, we calculate these elements for BaF via nuclear shell-model methods and extract limits on nucleon EDMs from current molecular EDM experiments. The framework provides a systematic way to interpret present and future paramagnetic molecular measurements in terms of hadronic CP violation.
