Probing Gravitino Dark Matter with PAMELA and Fermi
Wilfried Buchmüller, Alejandro Ibarra, Tetsuo Shindou +2
We analyze the cosmic-ray signatures of decaying gravitino dark matter in a model independent way based on an operator analysis. Thermal leptogenesis and universal boundary conditi…

Cosmic Rays from Leptophilic Dark Matter Decay via Kinetic Mixing
A. Ibarra, A. Ringwald, D. Tran +1
If interpreted in terms of decaying dark matter, the steep rise in the positron fraction of cosmic rays above 10 GeV, as observed by the PAMELA experiment, suggests an underlying p…
