Search for Boosted Dark Matter Interacting With Electrons in Super-Kamiokande

Understand

A search for boosted dark matter using 161.9 kiloton-years of Super-Kamiokande IV data is presented.

• We search for an excess of elastically scattered electrons above the atmospheric neutrino background, with a visible energy between 100 MeV and 1 TeV, pointing back to the Galactic Center or the Sun.
• No such excess is observed.
• Limits on boosted dark matter event rates in multiple angular cones around the Galactic Center and Sun are calculated.
