| Summary: | The neutrino mass ordering (NMO) is one of the fundamental questions in neutrino physics. This can be unraveled by next-generation neutrino detectors such as JUNO and KM3NeT-ORCA. JUNO is a medium-baseline (53 km) reactor experiment which could be sensitive to the NMO by investigating the interference effects between fast oscillations in oscillated electron-antineutrino spectrum. KM3NeT-ORCA is the Mton-scale water Cherenkov detector under construction in the Mediterranean Sea abyss. It can determine the NMO by probing Earth matter effect on atmospheric neutrinos. When measuring $\Delta m^2_{31}$ with a wrong ordering assumption, the best fit values are different between the two experiments. This tension could help enhancing the sensitivity to NMO in a joint fit. In this poster, the possibility of NMO determination from a combined analysis of JUNO and KM3NeT-ORCA is presented. |
