KM3NeT: Status, results and science goals — Matthias Bissinger and •Jutta Schnabel for the ANTARES-KM3NeT-Erlangen collaboration — Erlangen Centre for Astroparticle Physics, Erwin-Rommel-Str. 1, 91058 Erlangen, Germany

The research infrastructure KM3NeT is currently under construction off shores of France and Italy. The two main objectives of KM3NeT are investigating fundamental aspects of neutrino physics as well as the discovery and analysis of the most powerful cosmic accelerators via their neutrino signal. The deep-sea Cherenkov detectors, ORCA and ARCA, consist of technically identical detector modules but with different instrumentation densities. KM3NeT/ORCA will allow us to determine the oscillation probabilities of GeV-scale neutrinos produced in Earth’s atmosphere and thus to constrain the neutrino mass hierarchy. KM3NeT/ARCA’s instrumented sea volume of one cubic kilometer is much larger compared to ORCA. ARCA will detect neutrinos of energies from TeV to beyond PeV and thus of galactic origin and way beyond. Combined with the existing neutrino telescopes KM3NeT will complete our neutrino field of view to the full sky. The talk will summarise the current construction status of KM3NeT, the results achieved by investigating the data recorded over the past years, and the scientific discovery potential of the upcoming years.
