Baryogenesis requires large CPV phases, while said phases are constrained by electric dipole moment (EDM) experiments.
In the general two Higgs doublet model (g2HDM), without \(Z_{2} \) symmetry, EWBG can be achieved while evading EDM bounds.
In this study, we explore the g2HDM contributions to electron EDM (eEDM) and neutron EDM (nEDM), and review the future prospects in the experiment front.
In particular, we show that the combined eEDM-nEDM results can not only provide crucial bound on the top Yukawa-driven baryogenesis explanation in g2HDM, but are poised for discovery as experimental precision increases within the next decade or so.
