Description
The Nature of Dark Matter is, still, a widely open question that allows for very different anwers. One option is represented by particles that do interact gravitationally (as hinted by experiments), albeit with a coupling with gravity enhanced by an underlying extra-dimensional space-time. Several options have been proposed, either within a WIMPy or FIMPy approach, with different possibility for the geometry of the 5D space-time. I will shortly review these options and their experimental constraints, focusing eventually in a recent proposal of a Randall-Sundrum 5D setup with three branes that avoid most of the collider bounds while still producing the required amount of DM relic abundance.
