The Neutron EDM in the SM : A Review

Abstract

We review the status of the electric dipole moment (EDM) of neutron in the Standard Model (SM). The contributions of the strong and electroweak interactions are discussed seperately. In each case the structure of the Lagrangian and the sources of CP violation are specified, and calculational details are given subsequently. These two contributions to the neutron EDM exist in any extension of the SM including supersymmetry, two--doublet models as well as models with more than three generations of fermions. We do not discuss the EDM in such extensions; however, we briefly summarize their predictions with a detailed account of the related literature.
