Contribution

It introduces the first ten-year IceCube analysis for dark matter annihilation and predicts P-ONE's capability to significantly improve detection sensitivity beyond current limits.

Findings

IceCube sets more stringent bounds on dark matter annihilation.

P-ONE could exceed gamma-ray search sensitivities in 1-10 TeV range.

P-ONE may reach thermal relic abundance sensitivity.

Abstract

We present a new search for weakly interacting massive particles utilizing ten years of public IceCube data, setting more stringent bounds than previous IceCube analysis on massive dark matter to neutrino annihilation. We also predict the future potential of the new neutrino observatory, P-ONE, showing that it may even exceed the sensitivities of gamma-ray searches by about 1-2 orders of magnitude in 1-10 TeV regions. This analysis considers the diffuse dark matter self-annihilation to neutrinos via direct and indirect channels, from the galactic dark matter halo and extra-galactic sources. We also predict that P-ONE will be capable of pushing these bounds further than IceCube, even reaching the thermal relic abundance utilizing a galactic center search for extended run-time.
