Enhanced Sensitivity to Dark Matter Self-annihilations in the Sun using Neutrino Spectral Information

Understand

Self-annihilating dark matter gravitationally captured by the Sun could yield observable neutrino signals at current and next generation neutrino detectors.

• By exploiting such signals, neutrino detectors can probe the spin-dependent scattering of weakly interacting massive particles (WIMPs) with nucleons in the Sun.
• We describe a method how to convert constraints on neutrino fluxes to a limit on the WIMP-nucleon scattering cross section.
• In this method all neutrino flavors can be treated in a very similar way.
