Descripción
The standard model with three flavor neutrino oscillations is supported by the majority of neutrino oscillation data. However, a few experiments have observed anomalies, which are difficult to accommodate within the three flavour framework. One possible explanation of some anomalies is to postulate the existence of light sterile neutrinos.
Neutrino telescopes such as ANTARES and KM3NeT are promising detectors to probe the sterile neutrino hypothesis using atmospheric neutrinos. ANTARES is the largest deep-sea neutrino telescope, located in the Mediterranean Sea, in operation since 2008 in its full configuration. KM3NeT, now under construction in the Mediterranean Sea, is a next-generation network of water Cherenkov detectors. When completed, it will consist of two separate building blocks: ARCA (Astroparticle Research with Cosmics in the Abyss), optimized for high-energy neutrino astronomy, and ORCA (Oscillation Research with Cosmics in the Abyss) designed for neutrino oscillation studies in the GeV energy range. In this contribution, upper limits with 10 years of ANTARES data and ORCA sensitivities to the active-sterile mixing angles (θ14, θ24, θ34) in the (3+1) flavor model are presented.
