Résumé |
Numerous models of particle dark matter have been proposed, many of which remain
viable given current experimental and observational constraints. Minimal dark matter
is an extremely attractive option since it envisions the addition of a single SU(2)
multiplet to the standard model, rather than a complicated array of particles and
interactions. However, experimental limits already rule out a subset of minimal dark
matter possibilities and are approaching the predicted phase space of the remaining
candidates. We consider extensions to the minimal dark matter paradigm, particularly
a combination of two multiplets with a Higgs coupling, and the non-perturbative
effects which may alleviate this experimental pressure. |
