KM3NeT highlights

The KM3NeT Collaboration aims at the discovery and subsequent observation of high-energy neutrino sources in the Universe and at the determination of the neutrino mass hierarchy. The KM3NeT technologies, current status and expected performances are reported. The ARCA detector is described and its perspectives for detection of high energy neutrinos signals from different candidate sources are discussed. The ORCA detector and its expected significance for the mass hierarchy determination by means of the measurement of passing through Earth atmospheric neutrinos are also presented.
