Description

One of the main characteristic of the DM particle is that it is stable under cosmological time scales. We will review various new ideas which have been proposed recently to understand this stability from first principles rather than, as often done, by assuming an ad hoc global symmetry. This covers the remnant global symmetry of a gauge symmetry, hidden vector, heavy stable pions, unbroken gauge symmetry, ... frameworks. The associated phenomenology, unusual in some cases, will be discussed.
