Determining the nature of Dark Matter (DM) is among the main goals of multiple current and future experiments. An intriguing possibility is that Dark Matter arises as the massive mediator of a new force. 

I will present a new class of renormalizable models consisting of a dark SU(2) gauge sector, in which a massive vector boson is the DM candidate. The dark sector is connected to the Standard Model through a Vector-Like fermion mediator, and thus does not necessarily require a Higgs portal. These models have a large number of applications with significant implications for cosmology, collider physics and flavour observables, including potential roles in the explanation of current anomalies, such as the muon g-2 or the mass of the W boson.
