# Search for Neutrinos from Dark Matter Self-Annihilations in the center of the Milky Way with 3 years of IceCube/DeepCore

## TL;DR

This study used 3 years of IceCube data to search for neutrinos from dark matter self-annihilations in the Milky Way's center, setting new upper limits on annihilation cross sections for dark matter particles between 10 GeV and 1 TeV.

## Contribution

First comprehensive search for neutrinos from dark matter self-annihilations in the Milky Way using IceCube data, establishing the most stringent limits in the 10-100 GeV mass range.

## Key findings

- No significant neutrino excess detected.
- Set upper limits on annihilation cross section for dark matter masses 10 GeV to 1 TeV.
- Most stringent limits for 10-100 GeV dark matter particles.

## Abstract

We present a search for a neutrino signal from dark matter self-annihilations in the Milky Way using the IceCube Neutrino Observatory (IceCube). In 1005 days of data we found no significant excess of neutrinos over the background of neutrinos produced in atmospheric air showers from cosmic ray interactions. We derive upper limits on the velocity averaged product of the dark matter self-annihilation cross section and the relative velocity of the dark matter particles $\langle\sigma_{\text{A}}v\rangle$. Upper limits are set for dark matter particle candidate masses ranging from 10 GeV up to 1 TeV while considering annihilation through multiple channels. This work sets the most stringent limit on a neutrino signal from dark matter with mass between 10 GeV and 100 GeV, with a limit of $1.18\cdot10^{-23}\text{cm}^3\text{s}^{-1}$ for 100 GeV dark matter particles self-annihilating via $\tau^+\tau^-$ to neutrinos (assuming the Navarro-Frenk-White dark matter halo profile).
