SU(2)_N Model of Vector Dark Matter with a Leptonic Connection

Models of fermion and scalar dark matter abound. Here we consider instead vector dark matter, from an SU(2)_N extension of the standard model. It has a number of interesting properties, including a possible implementation of the inverse seesaw mechanism for neutrino mass. The annihilation of dark matter for calculating its relic abundance in this model is not dominated by its cross section to standard-model particles, but rather to other new particles which are in thermal equilibrium with those of the standard model.
