Status and physics results of the KM3NeT experiment

The KM3NeT submarine telescopes, currently under construction in the depths of the Mediterranean Sea, will enable the study of the Universe using neutrinos, the most elusive subatomic particles, as probe to investigate the depths of the Cosmos. KM3NeT-ARCA will study galactic and extra-galactic sources of very high energy neutrinos, thus operating in the field of the so-called “multi-messenger astronomy”. The detection of neutrinos from an astrophysical source can provide important information on the emission mechanisms of these objects. KM3NeTORCA will instead deal with a basic physics study: the mass hierarchy of neutrinos. This contribution will describe the components of the two detectors and the first measurements carried out. In addition, the sensitivities of KM3NeT for several fundamental measurements will be described, such as cosmic neutrino fluxes from diffuse and point-like astrophysical sources and neutrino mass ordering.
