Electroweak Multiplets as Dark Matter candidates: A brief review

High Energy Physics - Phenomenology 2024-05-13 v1 Cosmology and Nongalactic Astrophysics

Abstract

I provide a thorough review of the theoretical and experimental status of ElectroWeak multiplets as Dark Matter candidates, serving as the prototype of Weakly Interacting Massive Particles (WIMPs) Dark Matter. Specifically, the examination includes both real SU(2) representations with zero hypercharge and complex ones with Y0Y\neq 0. For the first time, all calculable thermal masses for scalar and fermionic WIMPs are computed, incorporating significant non-perturbative non-relativistic effects such as Sommerfeld enhancement and the formation of WIMP bound states. WIMP masses of few hundred TeV are shown to be compatible both with ss-wave unitarity of the annihilation cross-section, and perturbativity. Additionally, a strategy is outlined for probing these scenarios in the next generation of experiments.
