Electron Electric Dipole Moment fromCPViolation in the Charged Higgs Sector

The leading contributions to the electron (or muon) electric dipole moment due to $\mathrm{CP}$ violation in the charged Higgs sector are at the two–loop level. A careful model-independent analysis of the heavy fermion contribution is provided. We also consider some specific scenarios to demonstrate how charged Higgs sector $\mathrm{CP}$ violation can naturally give rise to large electric dipole moments. Numerical results show that the electron electric dipole moment in such models can lie at the experimentally accessible level.
