First observation of electron antineutrinos from nuclear reactors at Super-Kamiokande

K. Abe, Y. Asaoka, M. Harada +244

In 2020, Super-Kamiokande entered the SK-Gd phase, improving its sensitivity to low-energy electron antineutrinos through the detection of neutrons captured on gadolinium dissolved…

Search for the $^{16} O (ppp) \to^{13} C π^{+} π^{+} e^{+}$ Decay Mode in Super-Kamiokande Using Machine Learning Techniques

Kamiokande Collaboration, J. Feng, K. Abe +296

We report a new partial lifetime limit of $4.2 \times 1 0^{32}$ years for the trinucleon decay mode $^{16} O (ppp) \to^{13} C π^{+} π^{+} e^{+}$ , obtained from a searc…

Search for proton decay into a single charged antilepton and a massless invisible particle using the full pure water data set of Super-Kamiokande

Kamiokande Collaboration, Y. M. Liu, K. Terada +244

A search for proton decay via $p \to l^{+} + X$ , where $l^{+}$ is a positively charged lepton and $X$ is an invisible, massless, neutral particle, was performed using a 401~kt…

TeV-scale neutrino cross-section measurement using upward through-going muons in Super-Kamiokande

N. Bhuiyan, K. Abe, Y. Asaoka +248

Neutrinos provide a unique probe of both particle physics and the high-energy universe, traversing astronomical distances with minimal interaction. Their charged-current scattering…

In-situ high voltage generation with Cockcroft-Walton multiplier for xenon gas time projection chamber

Shinichi Akiyama, Junya Hikida, Masashi Yoshida +17

We have newly developed a Cockcroft-Walton (CW) multiplier that can be used in a gas time projection chamber (TPC). A TPC requires a high voltage to form an electric field that dri…

High-pressure xenon gas time projection chamber with scalable design and its performance at around the Q value of $^{136}$ Xe double-beta decay

Masashi Yoshida, Kazuhiro Nakamura, Shinichi Akiyama +18

We have been developing a high-pressure xenon gas time projection chamber (TPC) to search for neutrinoless double beta ( $0 ν β β$ ) decay of $^{136}$ Xe. The unique feature of this TPC…
