Search for dinucleon decay into pions at Super-Kamiokande
J. Gustafson, K. Abe, Y. Haga +119
A search for dinucleon decay into pions with the Super-Kamiokande detector has been performed with an exposure of 282.1 kiloton-years. Dinucleon decay is a process that violates ba…
Search for Trilepton Nucleon Decay via and in the Super-Kamiokande Experiment
V. Takhistov, K. Abe, Y. Haga +124
The trilepton nucleon decay modes and violate by two units. Using data from a 273.4 kiloton year exposure of Super-…
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…
Search for Nucleon and Dinucleon Decays with an Invisible Particle and a Charged Lepton in the Final State at the Super-Kamiokande Experiment

Search results for nucleon decays , , (where is an invisible, massless particle) as well as dinucleon decays $np \…
Atmospheric neutrino oscillation analysis with external constraints in Super-Kamiokande I-IV
Kamiokande Collaboration, K. Abe, C. Bronner +178
An analysis of atmospheric neutrino data from all four run periods of \superk optimized for sensitivity to the neutrino mass hierarchy is presented. Confidence intervals for $Îm^2…
Solar Neutrino Measurements in Super-Kamiokande-IV
Kamiokande Collaboration, K. Abe, Y. Haga +167
Upgraded electronics, improved water system dynamics, better calibration and analysis techniques allowed Super-Kamiokande-IV to clearly observe very low-energy 8B solar neutrino in…

Kamiokande Collaboration, K. Abe, Y. Haga +125
We present limits on sterile neutrino mixing using 4,438 live-days of atmospheric neutrino data from the Super-Kamiokande experiment. We search for fast oscillations driven by an e…
Search for neutrinos from annihilation of captured low-mass dark matter particles in the Sun by Super-Kamiokande
Kamiokande Collaboration, K. Choi, K. Abe +110
Super-Kamiokande (SK) can search for weakly interacting massive particles (WIMPs) by detecting neutrinos produced from WIMP annihilations occurring inside the Sun. In this analysis…
