In particular, a very well-motivated case is that of a new \"dark\" massive vector gauge boson mediator. The mass term for such mediator is most naturally obtained by a \"dark Higgs mechanism\" which leads to the presence of an often long-lived dark Higgs boson whose mass scale is the same as that of the mediator. We study the phenomenology and experimental constraints on two minimal, self-consistent dark sectors that include such a light dark Higgs boson.
