Abstract
We construct extended Higgs-boson models of soft CP-invariance violation arising from scalar-pseudoscalar mixing. Using the electric dipole moment of neutron as input, we find that the charged-lepton electric dipole moments scale as (mass. They are estimated to be 2.1×, 4.4×, and 1.8× e cm for electron, muon, and τ, respectively. An important test of this source of CP violation lies in the longitudinal polarizations of muon in η→μμ¯ and →μμ¯, which we estimate to be of the order of and , respectively.
