Results from the search for dark matter in the Milky Way with 9 years of data of the ANTARES neutrino telescope

TL;DR

This study used 9 years of ANTARES neutrino telescope data to search for dark matter annihilation signals in the Milky Way, setting new limits on the annihilation cross-section across various models and channels.

Contribution

It presents the first comprehensive search for dark matter annihilation in the Milky Way using ANTARES data spanning 2007-2015, considering multiple halo models and annihilation channels.

Findings

No excess signal was detected.

Limits on the dark matter annihilation cross-section were established.

Constraints are set across a wide range of WIMP masses and channels.

Abstract

Using data recorded with the ANTARES telescope from 2007 to 2015, a new search for dark matter annihilation in the Milky Way has been performed. Three halo models and five annihilation channels, $\rm WIMP + WIMP \to b \bar b, W^+ W^-, \tau^+ \tau^-, \mu^{+} \mu^{-}$ and $\nu \bar{\nu}$, with WIMP masses ranging from 50 $\frac{\text{GeV}}{\text{c}^2}$ to 100 $\frac{\text{TeV}}{\text{c}^2}$, were considered. No excess over the expected background was found, and limits on the thermally averaged annihilation cross--section were set.
