Monochromatic neutrino lines from sneutrino dark matter

Understand

We investigate the possibility of observing monochromatic neutrino lines originating from annihilation of dark matter.

• We analyse several astrophysical sources with overdensities of dark matter that can amplify the signal.
• As a case study, we consider mixed left and right handed sneutrino dark matter.
• We demonstrate that in the physically viable region of the model, one can obtain a prominent monochromatic neutrino line.
