Résumé :

Neutrino telescopes such as IceCube can be used to conduct indirect dark matter searches. A common assumption is that dark matter consists of Weakly Interacting Massive Particles (WIMPs), which are expected to produce Standard Model particles when they annihilate or decay. IceCube could then detect the neutrinos generated by these Standard Model particles. Since the Milky Way is expected to be immersed in a dark matter halo whose density increases towards its centre, the Galactic Centre is a designated target for indirect searches. In this contribution, we present the sensitivities of the search for dark matter in the Galactic Centre based on IceCube data, probing annihilation through νeνe, νμνμ, ντντ, μ+μ-, τ+τ-, W+W- and bb. We demonstrate that between WIMP masses of 5 GeV to 1 TeV, the sensitivity of IceCube to the velocity-averaged WIMP self-annihilation cross-section improves by an order of magnitude over previous searches with IceCube and other neutrino telescopes.
