Classes of complete dark photon models constrained by Z-physics
Dark Matter models that employ a vector portal to a dark sector are usually treated as an effective theory that incorporates kinetic mixing of the photon with a new U(1) gauge boson, with the Z boson integrated out. However, a more complete theory must employ the full SU(2)×L U(1)×Y U(1)Y′ gauge gro...
