The Complex Two-Higgs-Doublet Model (C2HDM) features an explicitly CP-violating scalar sector, making the electron electric dipole moment (eEDM) one of the most stringent probes of the model. The current limit of 4.1×10−30 e.cm already places strong constraints on CP-violating Higgs interactions, and future sensitivities are expected to improve by several orders of magnitude. This talk presents an updated analysis of the C2HDM parameter space under all current theoretical and experimental constraints. The calculation of the eEDM includes the contribution from the charm quark, which can be relevant in certain regions of the parameter space. Machine-learning techniques are employed to explore parameter regions that are difficult to access with traditional search strategies.
