TL;DR
The paper projects that the IceCube Upgrade will significantly improve sensitivity to low-mass dark matter annihilation signals from the Sun and Galactic Center, enabling stringent limits within three years.
Contribution
It provides the first sensitivity projections for the IceCube Upgrade targeting low-mass dark matter in the 3-500 GeV range from the Sun and Galactic Center.
Findings
IceCube Upgrade will achieve leading sensitivities to some dark matter models.
Three years of data will enable stringent limits on low-mass dark matter.
Projections cover dark matter masses from 3 GeV to 500 GeV.
Abstract
The IceCube Upgrade, an extension designed to enhance the IceCube Neutrino Observatory's detection of neutrinos with energies between 1 GeV and 500 GeV, will markedly improve IceCube's sensitivity to low-mass dark matter scenarios. In this study, we present sensitivity projections for the IceCube Upgrade to neutrino fluxes arising from dark matter annihilation. In particular, we consider dark matter with masses between 3 GeV to 500 GeV from both the core of the Sun and the Galactic Center. These projections indicate that the IceCube Upgrade will enable stringent limits on dark matter in this parameter space, achieving leading sensitivities to some dark matter models with only three years of data taking.
