Résumé |
I will discuss two novel proposals to probe Dark Matter (DM) with existing and upcoming data.
1. Cosmic rays constitute our arguably unique direct access to energy domains of 10 TeV and
above, and a wealth of data is delivered/expected from current/near-future telescopes
(ANTARES, IceCube, KM3NeT, HESSII, CTA, LHAASO, CALET,...). Heavy DM constitutes
therefore an ideal BSM target for these experiments: I will discuss the theory and
phenomenology of DM models that evade challenges like the so-called unitarity bound, and
propose related searches at such telescopes.
2. DM lighter than a GeV is notoriously a challenge for direct detection experiments. I will
propose to rely on the DM component that is unavoidably accelerated by scatterings of cosmic-
rays, that make it possible to detect DM at experiments with large energy thresholds and
volumes, like SuperKamiokande and DUNE. I will derive a new strong limit from public data and
discuss search strategies at current and future neutrino experiments. |
