Search for Magnetic Monopoles with the ANTARES Detector

Abstract : The ANTARES neutrino telescope is fully operational since May 2008. Located at a depth of ~ 2500 m in the Mediterranean Sea, 40 km off the Provencal coast, it comprises a large three-dimensional array of 885 Optical Modules deployed on 12 vertical lines. The telescope is aimed to observe high energy cosmic neutrinos through the detection of the Cherenkov light produced by up-going induced muons. Besides the detection of high energy neutrinos, the ANTARES telescope offers an opportunity to improve sensitivity to exotic cosmological relics, like magnetic monopoles. Monopoles are hypothetical particles initially predicted by Dirac in 1931, and reintroduced some decades later in a large class of Grand Unified Theories. Relativistic magnetic monopoles can emit a large amount of Cherenkov light when passing through matter, with intensity 8500 times higher than that radiated from a muon. Dedicated trigger algorithms and search strategies have been developed to search for such bright objects with the ANTARES detector. The data filtering, background rejection and final selection criteria will be described, as well as the expected sensitivity of ANTARES to exotic physics
