Abstract

We evaluate a new set of CP-violating two-loop Feynman diagrams involving W- and Z-bosons which give a large contribution to the electric dipole moment of the electron in a multi-Higgs model with spontaneous CP violation. This extends the work of Barr and Zee, who considered a two-loop diagram involving a top quark and showed that the effect is much larger than the standard one-loop contribution.
