【摘要】

Messengers of the infinitely small, neutrinos provide us with valuable insights into the fundamental laws of physics. Messengers of the infinitely large, traveling cosmological distances, they are privileged probes of cataclysmic astrophysical phenomena.

 KM3NeT, is a next generation neutrino telescope, located in the abysses of the Mediterranean Sea. It comprises a 3D matrix of photomultipliers that detect the Cherenkov light emitted by the charged particles produced when neutrinos interact inside or around the detector.

 I will briefly review the landscape of neutrino astronomy, focusing on the first cosmic signal detections recently obtained by IceCube, the constraints placed by ANTARES on its possible origin, and the excellent all-flavour potential of KM3NeT/ARCA, in particular for the search for neutrino sources in our Galaxy.

 I will then discuss the potential of KM3NeT/ORCA for the determination of the neutrino mass ordering through the study of atmospheric neutrinos in the GeV range. ORCA will also provide a high precision measurement of the neutrino mixing parameters, probe the Earth’s electron density profile, search for signatures of dark matter, sterile neutrinos and non-standard interactions. I will also discuss the potential of a neutrino beam from Protvino, Russia, to ORCA for the measurement of the CP-violating Dirac phase in the neutrino mixing matrix.
