Titre | Phenomenology of electroweak multiplets and the Galactic center excess |
Résumé | Electroweak multiplets are arguably among the simplest and best motivated WIMP dark matter candidates. I will review their relevant phenomenology in the light of current and future experimental searches. Predictions for searches at the high-luminosity LHC, and at an 100 TeV pp collider will be presented. Then, I will focus on indirect detection probes. I will compare the predictions of the model with the most recent bounds, discussing the impact of astrophysical uncertainties on current constraints. Finally, I will present predictions for future surveys. In the last part of the talk, I will focus on searches of a generic WIMP candidate with gamma-ray observations of the galactic center. Recently, an excess of photons has been reported from that region of the sky. This signal has been proposed as a possible hint of WIMP annihilations. Here, I will critically review its derivation. In particular, I explore realistic background diffusion models, accounting for a possible enhancement of cosmic-ray sources in the galactic center region. I will show that, taking into account the aforementioned ingredient, the astrophysical emission reproduces the morphological features of the data in a wide energy range, and there is no longer evidence on an excess. |
