Recent results with ANTARES, the first undersea neutrino telescope in the Mediterranean Sea

Abstract

The ANTARES detector is the largest undersea neutrino telescope. It is located at about 2500 m under the sea level in front of the Southern French coast, 40 km from Toulon. Its location in the Mediterranean Sea and the good optical properties of the sea water makes it an excellent tool to search for possible sources of neutrinos in the sky region of the Galactic Plane. Its angular resolution, ~ 0.4°, and the effective area for neutrinos coming from the Southern sky allow to put constraints on the possible interpretation of the recent IceCube cosmic neutrino signal. The ANTARES collaboration has developed a rich program of multi-messenger searches together with experiments sensitive to other cosmic messengers. ANTARES has also produced results on neutrinos coming from the annihilation of Dark Matter particles. In particular, the limits obtained for the spin-dependent WIMP-nucleon cross section overcome the existing direct-detection experiments. An overview of the most interesting and recent results obtained with ANTARES are discussed, together with the future perspectives of analyses.
