The Electric Dipole Moment of the W and Electron in the Standard Model

Abstract

I show that the electric dipole moment of the W-boson vanishes to two loop order in the Standard KM model. As a consequence, the electric dipole moment of the electron vanishes to three loop order. Including QCD corrections may give a non-vanishing result; I estimate d_W \approx 8 10^-31 ecm which induces an electron EDM \approx 8 10^-41 ecm, considerably smaller found in a previous calculation.
