Abstract:
A new U(1) gauge symmetry beyond standard model gauge symmetry and has no direct couplings to standard model particles is dubbed as a dark photon. It may couple to a rich dark sector. A kinetic mixing may provide a portal to make dark photon enlightened for show itself in our visible SM sector. In this talk I will discuss how the kinetic mixing can provide such information in both CP conserving and CP violating ways. Concrete theoretical models are constructed to demonstrate such possibilities.
