Indirect Searches for Decaying Dark Matter
Alejandro Ibarra, David Tran, Christoph Weniger
Numerous observations point towards the existence of an unknown elementary particle with no electromagnetic interactions, a large population of which was presumably produced in the…
Constraints on Hadronically Decaying Dark Matter
Mathias Garny, Alejandro Ibarra, David Tran
We present general constraints on dark matter stability in hadronic decay channels derived from measurements of cosmic-ray antiprotons.We analyze various hadronic decay modes in a…
Gamma-Ray Lines from Radiative Dark Matter Decay
Mathias Garny, Alejandro Ibarra, David Tran +1
The decay of dark matter particles which are coupled predominantly to charged leptons has been proposed as a possible origin of excess high-energy positrons and electrons observed…
Neutrino Signals from Dark Matter Decay
Laura Covi, Michael Grefe, Alejandro Ibarra +1
We investigate different neutrino signals from the decay of dark matter particles to determine the prospects for their detection, and more specifically if any spectral signature ca…
Cosmic-Ray Signatures of Dark Matter Decay
David Tran
In light of recent observations of an anomalous excess of high-energy positrons and electrons by the PAMELA and Fermi LAT experiments, we investigate exotic cosmic-ray signatures i…
Detecting Gamma-Ray Anisotropies from Decaying Dark Matter: Prospects for Fermi LAT
Alejandro Ibarra, David Tran, Christoph Weniger
Decaying dark matter particles could be indirectly detected as an excess over a simple power law in the energy spectrum of the diffuse extragalactic gamma-ray background. Furthermo…
