Indirect dark matter search in the Galactic Centre with IceCube

TL;DR

This paper reports on a search for neutrino signals from dark matter annihilation or decay in the Galactic Center using nearly a decade of IceCube-DeepCore data, focusing on low-energy neutrinos to constrain dark matter properties.

Contribution

It presents the first sensitivities on the dark matter self-annihilation cross-section in the 5 GeV to 8 TeV mass range using IceCube data optimized for low-energy neutrino detection.

Findings

Set new upper limits on dark matter annihilation cross-section.

Analyzed 9 years of IceCube-DeepCore data.

Focused on low-energy neutrino signals from the Galactic Center.

Abstract

It is assumed that dark matter can annihilate or decay into Standard Model particles which then can produce a neutrino flux detectable at IceCube. Such a signal can be emitted from the Galactic Center thanks to the high density of dark matter abundance being gravitationally captured. This analysis aims at searching for neutrino signals from dark matter annihilation and decay in the Galactic Center using $\sim$9 years of IceCube-DeepCore data with an optimized selection for low energy. In this contribution, we present the sensitivities on the thermally averaged dark matter self-annihilation cross-section for dark matter masses ranging from 5 GeV up to 8 TeV.
