Description

Dark matter (DM) particles can get captured inside the Sun due to DM-electron interaction. As the number of these captured DM particles increases, they can annihilate and produce different Standard Model (SM) final states. Neutrinos and anti-neutrinos produced from these final states can escape the Sun and reach ground-based neutrino telescopes. The latest data-sets from IceCube and DeepCore show no such excess of high energy neutrinos from the solar direction. Using these data-sets, we put stringent constraints on DM-electron scattering cross sections in the DM mass range 10 GeV to 105 GeV. Thus, near-future observations of the Sun by neutrino telescopes can potentially discover DM-electron interaction.
