Abstract: The hypothetical dark photon portal connecting the visible and dark sectors of the Universe has received considerable attention in recent years. Kinetic mixing between the Standard Model (SM) hypercharge gauge boson and a new U(1)X gauge boson plays an important role in making the portal mechanism to work. Previous studies of kinetic mixing has been focused on CP violating one, in this talk I report our results of first construct for a renormalizable model for CP-violating kinetic mixing that induces CP-violating non-Abelian kinetic mixing. I will discuss some related phenomenological consequences for kinetic mixing paying particular attention to CP violating effect show up in electron electric dipole moments (EDM) which makes future EDM searches an important probe of this scenario.
