Mirage in the sky: Nonthermal dark matter, gravitino problem, and cosmic ray anomalies
Recent anomalies in cosmic rays could be due to dark matter annihilation in our galaxy. In order to get the required large cross section to explain the data while still obtaining the right relic density, we rely on a nonstandard thermal history between dark matter freeze out and big-bang nucleosynthesis. …
