Description
We perform a comprehensive global analysis of the Complex Two-Higgs-Doublet
Model with softly broken Z₂ symmetry, identifying the intrinsic structure
of parameter regions supporting large CP violation under all current
constraints, including the JILA electron EDM bound. Type-I and Type-II
follow qualitatively distinct pathways: Type-I predicts $|d_e| ≳ 10⁻³¹$ e·cm,
fully testable by next-generation EDM experiments, while Type-II permits
nearly maximal Yukawa-sector CP mixing in the heavy Higgs sector.
We further uncover "hidden CP violation" in the Higgs alignment limit,
probeable through CP-violating heavy-scalar Yukawa couplings and the
robust $[H₂,H₃,Z]$ vertex at future colliders.
