Description
For many years, weak-scale supersymmetry has been the dominant framework for theoretically motivated dark-matter candidates. However, the lack of evidence for supersymmetry at the Large Hadron Collider pushes it to multi-TeV scales where viable dark-matter models rely on enhanced annihilations in order to account for the observed abundance. In contrast, non-supersymmetric grand unified theories (GUT) may also provide a dark-matter candidate. These theories are well motivated and lead to an interesting phenomenology. After reviewing some non-supersymmetric dark-matter frameworks, I will discuss the construction of viable GUT-inspired models.
