Beschreibung:
A nonzero electric dipole moment (EDM) of the neutron, proton, deuteron or helion or any finite system in general necessarily involves the breaking of fundamental symmetries, either by the presence of external fields - leading to the case of induced EDMs - or explicitly by the breaking of the discrete parity and time-reflection symmetries in the case of permanent EDMs. Recent results for the relevant matrix elements of nuclear EDM operators are presented and the relevance for disentangling underlying New Physics sources are discussed.
