Neutrino mass ordering determination through combined analysis with JUNO and KM3NeT/ORCA
International audience The neutrino mass ordering (NMO) is one of the fundamental questions in neutrino physics. KM3NeT/ORCA and JUNO are two neutrino oscillation experiments both aiming at measuring the NMO with different approaches: ORCA with atmospheric neutrinos traversing the Earth and JUNO wit...

International audience The neutrino mass ordering (NMO) is one of the fundamental questions in neutrino physics.
