Dark matter searches with the ANTARES neutrino telescope: constraints to CMSSM and mUED models

Abstract

ANTARES is the largest neutrino telescope Northern hemisphere. It consists of a threedimensional array of 885 photomultipliers to collect the Cherenkov light induced by relativistic muons produced in CC interactions of high energy neutrinos. One of the main scientific goals of the experiment is the search for dark matter. We present here the analysis of the recently unblinded data taken during 2007 and 2008 to look for a WIMP signal in the Sun. WIMPs are one of the most popular scenarios to explain the dark matter content of the Universe. They would accumulate in massive objects like the Sun or the Galactic Center and their self-annihilation would produce (directly or indirectly) high energy neutrinos detectable by neutrino telescopes. Contrary to other indirect searches (like with gamma rays or positrons), the search for neutrinos in the Sun is free from other astrophysical contributions, so the explanation of a potential signal in terms of dark matter would be much more robust. The results are interpreted within two theoretical frameworks: CMSSM and mUED.
