During the last few years we have constructed and studied the phenomenology of the Minimal Vector Dark Matter model (MVDM) where the Dark Matter is the neutral component of a massive vector field in the adjoint representation of SU(2) Left. However the MVDM is only an effective theory since it violates unitarity at a scale of some hundred TeV. In order, to make a UV completion of the model it is necessary to promote the massive vector field to a gauge field. In this seminar we will talk about our attempt to implement this program and we will describe a different approach taken by an independent group. At the end of the talk we will see how a gauge field (i.e. a force carrier) can "materialize", that is, how it can be transformed into a field which behaves like matter.
