Abstract

A search for high-energy neutrinos coming from thedirection of the Sun has been performed using the data recorded bythe ANTARES neutrino telescope during 2007 and 2008. The neutrino selectioncriteria have been chosen to maximize the selection of possible signals produced bythe self-annihilation of weakly interacting massive particlesaccumulated in the centre of the Sun with respect to the atmospheric background. After data unblinding,the number of neutrinos observed towards the Sun was found to be compatible with backgroundexpectations. The 90% CL upper limits in terms of spin-dependent and spin-independentWIMP-proton cross-sections are derived and compared to predictions of two supersymmetricmodels, CMSSM and MSSM-7. The ANTARES limits are comparable with those obtained by otherneutrino observatories and are more stringent than those obtained by direct searchexperiments for the spin-dependent WIMP-proton cross-section in the case of hardself-annihilation channels (W+W−, τ+τ−).
