Dark matter model selection and the ATIC/PPB-BETS anomaly
2009
We argue that we may be able to sort out dark matter models in which electrons are generated through the annihilation and/or decay of dark matter, by using a fact that the initial energy spectrum is reflected in the cosmic-ray electron flux observed at the Earth even after propagation through the Galactic magnetic field. To illustrate our idea we focus on three representative initial spectra: monochromatic, flat and double-peak ones. We find that those three cases result in significantly different energy spectra, which may be probed by the Fermi satellite in operation or an up-coming cosmic-ray detector such as CALET.
