First Joint Oscillation Analysis of Super-Kamiokande Atmospheric and T2K Accelerator Neutrino Data

K. Abe, Y. Hayato, K. Hiraide, K. Hosokawa et autres

The Super-Kamiokande and T2K Collaborations present a joint measurement of neutrino oscillation parameters from their atmospheric and beam neutrino data. It uses a common interaction model for events overlapping in neutrino energy and correlated detector systematic uncertainties between the two datasets, which …

Measurements of the charge ratio and polarization of cosmic-ray muons with the Super-Kamiokande detector

Haruki Kitagawa, Tomoaki Tada, K. Abe, C. Bronner et autres

We present the results of the charge ratio ( R ) and polarization ( P0μ ) measurements using decay electron events collected between September 2008 and June 2022 with the Super-Kamiokande detector. Because of its underground location and long operation, we are …

Second gadolinium loading to Super-Kamiokande

Kazuki ABE, C. Bronner, Y. Hayato, K. Hiraide et autres

The first loading of gadolinium (Gd) into Super-Kamiokande in 2020 was successful, and the neutron capture efficiency on Gd reached 50%. To further increase the Gd neutron capture efficiency to 75%, 26.1 tons of Gd2(SO4)3⋅8H2O was additionally loaded into Super-Kamiokande (SK) from …

Solar neutrino measurements using the full data period of Super-Kamiokande-IV

Kazuki ABE, C. Bronner, Y. Hayato, K. Hiraide et autres

An analysis of solar neutrino data from the fourth phase of Super-Kamiokande~(SK-IV) from October 2008 to May 2018 is performed and the results are presented. The observation time of the data set of SK-IV corresponds to $2970$~days and the total live time …

Erratum: Search for Cosmic-Ray Boosted Sub-GeV Dark Matter Using Recoil Protons at Super-Kamiokande [Phys. Rev. Lett. 130 , 031802 (2023)]

Kazuki ABE, Y. Hayato, K. Hiraide, K. Ieki et autres

The SK limit in Fig. 3 of this Letter was too constraining by a factor of 20 due to a unit conversion error.This error was limited to Fig. 3 and a discussion paragraph.All other conclusions remain unchanged.The corrected figure is included in …

Improvement of Coding Efficiency Method Based on Super-Resolution by Learing Decoded Images in HEVC

Katsuyuki Yoshizuka, Y. Kashiwagi, Gen Fujita

Recently, high-resolution videos such as 4K and 8K have become increasingly popular, leading to a significant increase in video data size. Consequently, techniques for more efficient video compression are needed. One approach to address this issue is to downsample the video image …

Search for Cosmic-Ray Boosted Sub-GeV Dark Matter Using Recoil Protons at Super-Kamiokande

Kazuki ABE, Y. Hayato, K. Hiraide, K. Ieki et autres

We report a search for cosmic-ray boosted dark matter with protons using the 0.37 megaton×years data collected at Super-Kamiokande experiment during the 1996-2018 period (SKI-IV phase). We searched for an excess of proton recoils above the atmospheric neutrino background from the vicinity …

Search for proton decay via p → μ + K 0 in 0.37 megaton-years exposure of Super-Kamiokande

R. Matsumoto, Kazuki ABE, Y. Hayato, K. Hiraide et autres

We searched for proton decay via $p\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{K}^{0}$ in $0.37\text{ }\text{ }\mathrm{Mton}\ifmmode\cdot\else\textperiodcentered\fi{}\mathrm{years}$ of data collected between 1996 and 2018 from the Super-Kamiokande water Cherenkov experiment. The selection criteria were defined separately for ${K}_{S}^{0}$ and ${K}_{L}^{0}$ channels. No significant event excess has been observed. …

Searching for Supernova Bursts in Super-Kamiokande IV

M. Mori, Kazuki ABE, Y. Hayato, K. Hiraide et autres

Abstract Super-Kamiokande has been searching for neutrino bursts characteristic of core-collapse supernovae continuously, in real time, since the start of operations in 1996. The present work focuses on detecting more distant supernovae whose event rate may be too small to trigger in …

Pre-supernova Alert System for Super-Kamiokande

Lucas Nascimento Machado, Kazuki ABE, Y. Hayato, K. Hiraide et autres

Abstract In 2020, the Super-Kamiokande (SK) experiment moved to a new stage (SK-Gd) in which gadolinium (Gd) sulfate octahydrate was added to the water in the detector, enhancing the efficiency to detect thermal neutrons and consequently improving the sensitivity to low energy …
