Multistep cascade annihilations of dark matter and the Galactic Center excess
If dark matter is embedded in a nontrivial dark sector, it may annihilate and decay to lighter dark-sector states which subsequently decay to the standard model. Such scenarios—with annihilation followed by cascading dark-sector decays—can explain the apparent excess GeV gamma rays identified in the...
