Description
In light of increasing constraints on WIMP models, exciting alternatives have begun to gain traction. One example is freeze-in models which rely on extremely small dark-visible couplings to produce dark matter from the visible sector. Such non-standard dark matter models can be probed (despite the tiny couplings) by direct detection experiments if they include a light mediator. Moreover, thermal effects lead to a mixing of the mediator with Standard Model gauge bosons, resulting in novel phenomenology.
In this talk, I will focus on a dark photon model arising from a B-L symmetry. I will detail how the parameter space for such models can be probed complementarily at colliders, direct detection experiments and from astrophysics.
