Abstract:

High-energy neutrinos constitute a key probe at the interface of particle physics, astrophysics, and cosmology. The ANTARES detector has demonstrated the viability of large-scale neutrino detection in the deep sea, delivering competitive limits on diffuse fluxes, point-source searches, and multi-messenger correlations.

The next-generation KM3NeT infrastructure significantly extends this program through two optimized detectors: KM3NeT/ORCA, dedicated to atmospheric neutrino oscillation studies and mass ordering sensitivity, and KM3NeT/ARCA, designed for TeV–PeV neutrino astronomy.

I will present the main scientific outcomes of ANTARES and discuss early KM3NeT results, including the detection of an extreme-energy neutrino candidate (KM3-230213A, ~120 PeV reconstructed muon energy). Such events may provide access to cosmogenic neutrino fluxes and constrain models of ultra-high-energy cosmic-ray sources.

KM3NeT is expected to deliver unprecedented sensitivity across a broad energy range, enabling both precision oscillation measurements and the identification of high-energy neutrino sources.
