Title: Electron EDM in the Complex Two-Higgs Doublet Model

Abstract: 
 
In this talk, I summarize features of a complete two-loop calulation of the electron EDM in the C2HDM, and demonstrate how a gauge independent result is achieved.  I also constrast my result with an earlier calculation based on the pinch technique.  I then discuss its behavior in the decoupling limit (heavy new particles), and make contact with a recent analysis based on EFT.  This talk is based on https://arxiv.org/abs/2009.01258.
