Description
The Electric Dipole Moment of the electron (eEDM) is typically investigated in experiments using paramagnetic molecules. However, the physical observable in these searches consists in a linear combination of CP-violating interactions, rather than the eEDM alone, which is commonly referred to as the equivalent EDM of the system. In this talk, I assume the presence of heavy CP-odd new physics and parametrize its effects in the Standard Model Effective Field Theory (SMEFT). I then examine how the SMEFT operators contribute to the equivalent EDM in paramagnetic systems, focusing on the leading dimension-six and one-loop contributions, while also including selected two-loop mixing effects and dimension-eight terms. I conclude by showing that eEDM experiments are sensitive to a wider set of SMEFT operators than previously recognized.
