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, WIMP+WIMP→bb¯,W+W−,τ+τ−,μ+μ− and νν¯, with WIMP masses ranging from 50 GeVc2 to 100 TeVc2, were considered. No excess over the expected background was found, and limits on the thermally averaged annihilation cross-section were set.

Highlights

A wide variety of observations supply evidence for the existence of dark matter (DM) [1,2]

Summary

Introduction

A wide variety of observations supply evidence for the existence of dark matter (DM) [1,2]. A common hypothesis is to consider dark matter to be made of new, unknown particles. The assumption that these particles are a thermal relic of the Big Bang leads to the conclusion that they are weakly interacting massive particles (WIMPs). Neutrino telescopes may play a paramount role in the search for WIMPs via their annihilation products, because of their clean signals and low expected backgrounds. In this paper the results from the search for dark matter in the Milky Way using data recorded with the ANTARES neutrino telescope from 2007 to 2015, with a total live time of 2102 days are presented. More recent parameters for the DM halo in the Milky Way are used
