We update the flavor-violating constraints on the charged Higgs sector of the 2-Higgs Doublet Model Type-III (2HDM-III), using a four-zero texture in the Yukawa matrices. We give a generic Lagrangian of the 2HDM-III. In order to show the…

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.…
