Neutrino mass ordering determination through combined analysis with JUNO and KM3NeT/ORCA
International audience The determination of neutrino mass ordering (NMO) is one of the prime goals of several neutrino experiments. KM3NeT/ORCA and JUNO are two next-generation neutrino oscillation experiments both aiming at addressing this question. ORCA can determine the NMO by probing Earth matte...
