Physics Colloquium: Hunting for WIMPs with Charged Cosmic Rays

Main content

The existence of dark matter in the universe is well-established, but its origin still remains unknown. In one of the most plausible scenarios, the dark matter is formed by Weakly Interacting Massive Particles (WIMPs) which survived as thermal relics from the early universe. If such WIMPs existed they would undergo pair-annihilation in the halo surrounding our galaxy. The resulting energetic particles would be observable in the cosmic radiation. I will describe the most recent efforts to detect the imprints of WIMPs in the spectra of the cosmic antimatter.
