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.

This contribution presents the potential of determining the NMO through a combined analysis of JUNO and ORCA data. In a joint fit, the NMO sensitivity is enhanced beyond the simple sum of the sensitivities of each experiment due to the tension between the respective Δm$_{31}^{2}$ best fit values obtained when the wrong ordering is assumed, together with good constraints on this parameter measurement by both experiments.
