Description
In this talk, my objective is to present the phenomenology of Electroweak multiplets as potential Dark Matter (DM) candidates in the coming years, with a specific focus on detection possibilities at the muon collider. To begin, I will delve into the thermal production mechanism in the early Universe and provide an overview of the current phenomenological landscape concerning the search for Weakly Interacting Massive Particles (WIMPs). It is important to note that WIMPs continue to be a viable DM candidate with significant phenomenological implications in the foreseeable future. Subsequently, I will describe the main properties of Electroweak multiplets as DM candidates, which serve as prototypes for WIMP DM. Specifically, I will illustrate how to compute the thermal masses, taking into account significant non-perturbative non-relativistic effects such as the Sommerfeld enhancement and the formation of DM bound states. Finally, I will conclude with the phenomenology of EW multiplets by emphasizing that a synergy between cosmological probes and the muon collider is needed to say a final work on this crucial class of DM candidates.
