Description
Summary:International audience Neutrino Telescopes such as ANTARES and KM3NeT are promising candidates to probeexotic oscillation phenomena such as sterile neutrinos. ANTARES (Astronomy with a NeutrinoTelescope and Abyss Environmental RESearch) is the largest deep-sea neutrino telescope inoperation, covering an area of 0.01 km3and taking data since 2007. KM3NeT in totality ismuch more extended than ANTARES and it is under construction in the Mediterranean Sea.When completed, it will consist of two separate detectors: ARCA (Astroparticle Research withCosmics in the Abyss), optimised for high-energy neutrino astronomy, and ORCA (OscillationResearch with Cosmics in the Abyss) for neutrino oscillation studies with atmospheric neutrinos.ORCA will have an effective mass of 8 Mtons and a low neutrino energy detection threshold of1 GeV. For this reason it is a promising candidate to study neutrinos properties. Here we presentthe upper limits from ANTARES and sensitivities of ORCA to sterile neutrinos in the (3+1)model.
