Findings

Set new limits on dark matter spin-dependent interactions.

Constrained neutrino background from cosmic ray interactions with the Sun.

Analyzed 9.3 and 10.4 years of IceCube data.

Abstract

In this Letter, we present the results of a search for high-energy neutrinos produced by the annihilation of dark matter particles trapped in the Sun. Using 9.3 and 10.4 years of data from the DeepCore and IceCube neutrino detectors, we establish world-best limits for spin-dependent interactions between dark matter and Standard Model particles for dark matter masses from tens of GeV to tens of TeV. We additionally place constraints on the neutrino background produced by interactions of cosmic rays with the solar atmosphere.
