The Jiangmen Underground Neutrino Observatory (JUNO) is a multipurpose liquid scintillator-based neutrino experiment with a target mass of 20 kt. The detector is currently under construction and expected to be completed by the end of 2023. Its main goal is the determination of the neutrino mass ordering (MO), through a measurement of the oscillation pattern of reactor anti-neutrinos over a 53 km baseline. As the largest liquid-scintillator detector, JUNO will also be able to observe atmospheric neutrinos events in the GeV region and down to sub-GeV. Therefore, the sensitivity of JUNO to the neutrino mass ordering can be enhanced from 3 to at least 4 sigma in 6 years via a combined analysis of reactor anti-neutrinos with atmospheric neutrinos. Such an analysis requires a precise knowledge on the track of atmospheric neutrinos, which is challenging in terms of reconstruction of the isotropic scintillation light emitted in JUNO. To achieve this target performance, a novel track reconstruction technique based on the voxelized distribution of optical photon emissions is being developed. The current status of this method will be presented in this talk. |
