An analysis of atmospheric neutrino data from all four run periods \superk optimized for sensitivity to the mass hierarchy is presented. Confidence intervals $\Delta m^2_{32}$, $\sin^2 \theta_{23}$, \theta_{13}$ and $\delta_{CP}$ are presented normal inverted hypotheses based on alone. Additional constraints reactor $\theta_{13}$ published binned T2K muon disappearance electron appearance added fit give enhanced above parameters. Over range parameters allowed at 90% confidence level, favored...
Using 5326 days of atmospheric neutrino data, a search for tau appearance has been performed in the Super-Kamiokande experiment. measures normalization to be $1.47\ifmmode\pm\else\textpm\fi{}0.32$ under assumption normal hierarchy, relative expectation unity with oscillation.

The directionality information of incoming neutrinos is essential to atmospheric neutrino oscillation analysis since it directly related the baseline length. Large homogeneous liquid scintillator detectors, while offering excellent energy resolution, are traditionally very limited in their capabilities measuring event directionality. In this paper, we present a novel reconstruction method for events large detectors based on waveform and machine learning techniques. We demonstrate first time...

Hadrons produced in neutrino-nucleus interactions may re-scatter while propagating through the nuclear medium. Such re-scatters, often called Final State Interactions (FSI), can change charge and multiplicity of outgoing hadrons, as well altering their final state kinematics. A good description these processes is crucial for accurate measurements neutrino energy spectra – a key part oscillation analyses.
Abstract The Jiangmen Underground Neutrino Observatory (JUNO) is designed to determine neutrino mass ordering (NMO) using a large liquid scintillator detector located in southern China. While JUNO's NMO sensitivity mostly comes from reactor neutrinos, atmospheric oscillations JUNO can provide complimentary via matter effects, and enhance its overall joint analysis. flavor identification crucial oscillation measurements, but traditionally very difficult task detectors such as JUNO. In this...
The Jiangmen Underground Neutrino Observatory (JUNO) experiment is designed to measure the neutrino mass ordering (NMO) using a 20-kton liquid scintillator (LS) detector. Besides precise measurement of reactor neutrino’s oscillation spectrum, an atmospheric in JUNO offers independent sensitivity for NMO, which can potentially increase JUNO’s total joint analysis. In this contribution, we present novel multi-purpose reconstruction method neutrinos at few-GeV based on machine learning...
Used for both proton decay searches and neutrino physics, large water Cherenkov (WC) detectors have been very successful tools in particle physics. They are notable their masses charged detection capabilities. While current WC reconstruct tracks over a wide energy range, they cannot efficiently detect neutrons.
