KM3NeT-ORCA and JUNO combined sensitivity to the neutrino mass ordering

Description

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.

Mini-abstract

Combined fit of JUNO and KM3NeT-ORCA can enhance the sensitivity to the neutrino mass ordering.
