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

Understand

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.
