Description
The nature of dark matter remains one of the central puzzles in physics. Beyond traditional WIMPs, weakly interacting slim particles (WISPs) — such as axions, axion-like particles, dilatons, dark photons, and dark gravitons — emerge naturally in theories beyond the Standard Model, including string theory and modified gravity. Their ultra-light masses make them compelling wave-like dark matter candidates with rich phenomenology. This talk reviews their theoretical motivations, production mechanisms, and experimental searches across astrophysics and the laboratory, highlighting how upcoming efforts could soon unveil the origin of dark matter.
