Search for proton decay via $p \to e^{+} η$ and $p \to μ^{+} η$ with a 0.37 Mton-year exposure of Super-Kamiokande

Kamiokande Collaboration, N. Taniuchi, K. Abe +288

A search for proton decay into $e^{+} / μ^{+}$ and a $η$ meson has been performed using data from a 0.373 Mton $\cdot$ year exposure (6050.3 live days) of Super-Kamiokande. Compared to pre…

Measurement of the cosmogenic neutron yield in Super-Kamiokande with gadolinium loaded water

Kamiokande Collaboration, M. Shinoki, K. Abe +238

Cosmic-ray muons that enter the Super-Kamiokande detector cause hadronic showers due to spallation in water, producing neutrons and radioactive isotopes. Those are a major backgrou…

Neutron Tagging following Atmospheric Neutrino Events in a Water Cherenkov Detector

K. Abe, Y. Haga, Y. Hayato +301

We present the development of neutron-tagging techniques in Super-Kamiokande IV using a neural network analysis. The detection efficiency of neutron capture on hydrogen is estimate…

New Methods and Simulations for Cosmogenic Induced Spallation Removal in Super-Kamiokande-IV

Kamiokande Collaboration, S. Locke, A. Coffani +215

Radioactivity induced by cosmic muon spallation is a dominant source of backgrounds for $O (10)$ MeV neutrino interactions in water Cherenkov detectors. In particular, it…

Search for solar electron anti-neutrinos due to spin-flavor precession in the Sun with Super-Kamiokande-IV

Kamiokande Collaboration, K. Abe, C. Bronner +197

Due to a very low production rate of electron anti-neutrinos ( $ν ˉ_{e}$ ) via nuclear fusion in the Sun, a flux of solar $ν ˉ_{e}$ is unexpected. An appearance of $ν ˉ_{e}$ in solar…
