We show that dark matter could be made of massive gauge bosons whose stability doesn't require to impose by hand any discrete or global symmetry. Stability of gauge bosons can be guaranteed by the custodial symmetry associated to the gauge symmetry and particle content of the model. The particle content we consider to this end is based on a hidden sector made of a vector multiplet associated to a non-abelian gauge group and of a scalar multiplet charged under this gauge group. The hidden sector interacts with the Standard Model particles through the Higgs portal quartic scalar interaction in such a way that the gauge bosons behave as thermal WIMPS. This can lead easily to the observed dark matter relic density in agreement with the other various constraints, and can be tested experimentally in a large fraction of the parameter space. In this model the dark matter direct detection rate and the annihilation cross section can decouple if the Higgs portal interaction is weak.

The waning of the WIMP? A review of models, searches, and constraints (2017, background): “In the case of fermion DM the region surviving current 16 Dark matter a gauge boson of dark sector connected to the SM through the Higgs sector has been also proposed, for different DM production mechanisms, in [246, 247].”
Probing dark forces and light hidden sectors at low-energy e+e- colliders (2009, background): “The discussion of Section 3 is similar in spirit to the hadron collider phenomenology for Hidden Valleys [18, 19, 20, 21] and the Higgsed dark-sector models discussed in [8, 22, 23] (see also [24]).”
Semi-annihilation of dark matter (2010, background): “Such reactions are also allowed in models where dark matter is composed of non-Abelian gauge bosons [12, 13, 14].”
Accidental composite dark matter (2015, background): “J H E P 0 7 ( 2 0 1 5 ) 0 3 9 idea can be minimally realized by adding to the SM one extra multiplet that cannot have any Yukawa interaction with SM particles, and that contains a DM candidate ([1, 2]; a different proposal to get accidentally stable DM was presented by [3]).”

Dark matter and neutrino masses from a scale-invariant multi-Higgs portal (2015, background): “SU(2)X vector dark matter has been studied in [90–102] and in the context of classical scale invariance in [47,48,51,59].”
Dark nuclei. I. Cosmology and indirect detection (2014, background): “Generally speaking, the broad topology of both processes is that of so-called semi-annihilation [42–45], which has also arisen in other models [46–48].”
