Abstrakt:
KM3NeT is a multi-purpose neutrino observatory under construction in the Mediterranean Sea. It is composed of two Cherenkov detectors with different designs: ORCA, a compact and dense detector optimised for the high-statistic measurement of atmospheric neutrino physics in the 1- 100 GeV energy range, and ARCA, a set of two telescopes instrumenting a cubic kilometre to catch fluxes of extraterrestrial neutrinos from 100 GeV to 10 PeV. With a modular layout, KM3NeT takes data promptly upon deployment throughout its installation phase. Beyond astronomy and oscillation physics, KM3NeT searches for neutrinos produced in pair annihilations of dark matter. The Galactic Centre, which is thought to host the largest close-by over-density of dark matter, is in good visibility from the KM3NeT site, which gives this detector a unique opportunity to set limits on a signal of dark-matter induced neutrinos from this source. KM3NeT has the chance to investigate other effects of physics beyond the Standard Model through modifications that those induce to the flavour oscillation pattern of atmospheric neutrinos. A data set recorded with a partial configuration of KM3NeT has been analysed in search for non-standard interactions, neutrino decay, and neutrino quantum decoherence.
