Abstract

An analysis is presented of the possible existence of a second anomalous dipole moment of Dirac’s particle next to the angular one. It includes a discussion why, in spite of his own derivation, Dirac has denied its relevancy. It is shown why since then it has been overlooked and why it has vanished from leading textbooks. A critical survey is given on the reasons of its reject, including the failure of attempts to measure and the perceived violations of time reversal symmetry and charge-parity symmetry. Moreover, by reference from literature, the possible impact is discussed in the nuclear domain and in the gravitational domain.

Subject Areas

Comment: Better explanation of the difference between the electric dipole moment of an electron (eEDM) as defined in the Standard Model and Dirac's anomalous electric dipole moment of an electron (AEDM).
