Abstract: In this talk, I will briefly summarize the current collider constraints on dark photon in the Abelian and non-Abelian kinetic mixing models and show the sensitivities at future e^+e^- colliders. Motivated by the matter-antimatter asymmetry in the universe, we studied new CP-violating effects in the non-Abelian kinetic mixing model, which can contribute at the one-loop level to the fermion EDMs and be verified through the azimuthal angle asymmetry in the vector boson fusion process at the LHC. Finally, I will show the subtlety in the definition of a massless dark photon.
