Dark Matter candidates circa 2021: the WIMPs and beyond the WIMPs

by Marco CIRELLI (LPTHE Jussieu CNRS)


Almost a century after its discovery, Dark Matter has not been identified yet. Even worse, the candidates that were more promising a few years/decades ago, those that the community was betting to find “just around the corner", have not shown up in the ever-improving searches. Hence theorists have gone back to the drawing board and restarted exploring a wider range of possibilities. Many new ideas have been proposed, and some old ideas have been rediscovered. In this talk I will present a (necessarily biased and personal) view of some Dark Matter candidates. I will argue that the cherished WIMPs (Weakly Interacting Massive Particles) should not be dismissed yet, but also that other candidates are well motivated, interesting and worth looking for.
