Annihilation vs. decay: constraining dark matter properties from a gamma-ray detection
Annihilation vs. decay: constraining dark matter properties from a gamma-ray detection
Most proposed dark matter candidates are stable and are produced thermally in the early Universe. However, there is also the possibility of unstable (but long-lived) dark matter, produced thermally or otherwise. We propose a strategy to distinguish between dark matter annihilation and/or decay in the case that a clear signal …
