Dark Matter Decay to a Photon and a Neutrino: the Double Monochromatic Smoking Gun Scenario
Chaïmae El Aisati, Michael Gustafsson, Thomas Hambye +1
In the energy range from few TeV to 25 TeV, upper bounds on the dark matter decay rate into high energy monochromatic neutrinos have recently become comparable to those on monochro…
Neutral and Millicharged Dark Matter Decay into Gamma-Ray Lines
Tiziana Scarna
A gamma-ray line observation would be a strong hint towards the detection of dark matter. The possibility that a decay of the dark matter particle is responsible for the emission o…
Can a millicharged dark matter particle emit an observable gamma-ray line?
Chaïmae El Aisati, Thomas Hambye, Tiziana Scarna
If a gamma-ray line is observed in the near future, it will be important to determine what kind of dark matter (DM) particle could be at its origin. We investigate the possibility…
Effective Theory of Dark Matter Decay into Monochromatic Photons and its Implications: Constraints from Associated Cosmic-Ray Emission
Michael Gustafsson, Thomas Hambye, Tiziana Scarna
We show that there exists only a quite limited number of higher dimensional operators which can naturally lead to a slow decay of dark matter particles into monochromatic photons.…
What if Dark Matter Gamma-Ray Lines come with Gluon Lines?
Xiaoyong Chu, Thomas Hambye, Tiziana Scarna +1
In dark matter (DM) models, the production of a gamma line (or of a "box-shaped" gamma-ray spectrum) from DM annihilation proceeds in general from a loop diagram involving a heavy…
