Dark matter searches with IceCube

TL;DR

This paper reviews IceCube's search for dark matter through neutrino detection, presenting limits on particle interactions and annihilation rates based on data from partial detector configurations.

Contribution

It provides the first comprehensive analysis of dark matter search results from IceCube's 22- and 40-string configurations, including constraints on various dark matter candidates.

Findings

Set limits on muon flux from dark matter annihilation

Constrained spin-dependent cross-section with protons

Placed bounds on self-annihilation cross section

Abstract

The construction of the IceCube neutrino observatory is practically terminated. At the time of this writing, and with 79 strings taking data out of the 86 foreseen, we are one deployment season away from completion. The detector, however, has been taking data since 2006 in different partial configurations. We have evaluated these data for evidence of dark matter annihilations in the Sun, in the Galactic Center and in the Galactic Halo, searching for an excess neutrino flux over the expected atmospheric neutrino background. This contribution reviews the results of dark matter searches for WIMPs, Kaluza-Klein modes and superheavy candidates (Simpzillas), using the 22- and 40-string configurations of IceCube. The results are presented in the form of muon flux limits, constrains on the candidates' spin-dependent cross-section with protons, and constrains in the self-annihilation cross section. These results are presented in the context of direct searches and searches in space
