The Electric Dipole Moment of the electron in the decoupling limit of the aligned Two-Higgs Doublet Model

Understand

We present a discussion of model-independent contributions to the EDM of the electron.

• We focus on those contributions that emerge from a heavy scalar sector that is linearly realized.
• In particular, we explore the decoupling limit of the aligned 2HDM.
• In this model, Barr-Zee diagrams with a fermion loop produce logarithmically-enhanced contributions that are proportional to potentially large new sources of CP violation.
