Parametrizing the reconstruction performance of Super-Kamiokande in the Sub-GeV to TeV neutrino energy range

Super-Kamiokande is a paramount detector for studying atmospheric, astrophysical and accelerator neutrino physics. This work extracts and characterizes the neutrino reconstruction performance of Super-Kamiokande using the public data release from its latest atmospheric neutrino analysis. Energy and zenith angle reconstruction performances are derived and modeled for neutrinos spanning sub-GeV to TeV energies across different event samples and sample-specific and sample-aggregated performances are provided. These metrics enable realistic detector response modeling in phenomenological studies, establish benchmarks for evaluating alternative reconstruction algorithms, facilitate quantitative performance comparisons with other experiments, and provide a baseline performance model for the future Hyper-Kamiokande detector. This study represents the first publicly available comprehensive model to describe neutrino reconstruction in Super-Kamiokande in the Sub-GeV to TeV energies.
