1212.1290 (Guillaume Lambard)

Indirect dark matter search with the ANTARES neutrino telescope    [PDF]

Guillaume Lambard
Using the data recorded by the ANTARES neutrino telescope during 2007 and 2008, a search for high energy neutrinos coming from the direction of the Sun has been performed. The neutrino selection criteria have been chosen so as to maximize the rejection of the atmospheric background with respect to possible signals produced by the self-annihilation of weakly interactive massive particles accumulated in the centre of the Sun. After data unblinding, the number of neutrinos observed was found to be compatible with background expectations. The results obtained were compared to the fluxes predicted by the Constrained Minimal Supersymmetric Standard Model, and 90% upper limits for this model were obtained. Our limits are competitive with those obtained by other neutrino telescopes such as IceCube and SuperKamiokande, which give ANTARES limits for the spin-dependent WIMP-proton cross-section that are more stringent than those obtained by direct search experiments.
