Sensitivities of KM3NeT on decaying dark matter

Understand

The discovery of high-energy astrophysical neutrinos by IceCube has opened a new window to the Universe.

• However, the origin of these neutrinos is still a mystery, and some of them could be a result of dark matter interactions such as decay.
• Next generation gigaton water-Cherenkov neutrino telescope, KM3NeT, is expected to offer significantly improved energy resolution in the cascade channel, and advantageous viewing condition to the Galactic Center; both important for searches of dark matter decay signals.
• We study the sensitivity of KM3NeT on dark matter decays by performing a mock likelihood analysis for both cascade and track type events, taking into account both angular and energy information.
