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…

Search for proton decay via $p \to e^{+} π^{0} π^{0}$ and $p \to μ^{+} π^{0} π^{0}$ in 0.401 megaton-years exposure of Super-Kamiokande I-V

Kamiokande Collaboration, K. Abe, S. Abe +310

We searched for proton decay via $p \to e^{+} π^{0} π^{0}$ and $p \to μ^{+} π^{0} π^{0}$ in 0.401 megaton-years of data collected in all pure water detector phases of Super-Kamiokande…

Search for Diffuse Supernova Neutrino Background with 956.2 days of Super-Kamiokande Gadolinium Dataset

K. Abe, S. Abe, Y. Asaoka +245

We report the search result for the Diffuse Supernova Neutrino Background (DSNB) in neutrino energies beyond 9.3~MeV in the gadolinium-loaded Super-Kamiokande (SK) detector with $2…

Search for nucleon decay via $p \to ν π^{+}$ and $n \to ν π^{0}$ in 0.484 Mton-year of Super-Kamiokande data

Kamiokande Collaboration, S. Jung, K. Abe +243

We present the results of searches for nucleon decays via $p \to ν π^{+}$ and $n \to ν π^{0}$ using a 0.484 Mt $\cdot$ yr exposure of Super-Kamiokande I-V data covering the…

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…
