Measurement of the solar neutrino interaction rate below 3.49 MeV in Super-Kamiokande-IV

Kamiokande Collaboration, A. Yankelevich, K. Abe +250

Super-Kamiokande (SK) has observed $^{8} B$ solar neutrino elastic scattering at recoil electron kinetic energies ( $E_{kin}$ ) as low as 3.49 MeV to study neutrino flav…

Search for proton decay via $p \to e^{+} I ¨ ^{0} I ¨ ^{0}$ and $p \to I^¼^{+} I ¨ ^{0} I ¨ ^{0}$ in 0.401 megaton-years exposure of Super-Kamiokande I-V

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

We searched for proton decay via $p \to e^{+} I ¨ ^{0} I ¨ ^{0}$ and $p \to I^¼^{+} I ¨ ^{0} I ¨ ^{0}$ in 0.401 megaton-years of data collected in all pure water detector phases of Super-Kamiok…

Search for nucleon decay via $p \to I^½ I ¨ ^{+}$ and $n \to I^½ I ¨ ^{0}$ 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 $p \to I^½ I ¨ ^{+}$ and $n \to I^½ I ¨ ^{0}$ using a 0.484 Mt $\cdot$ yr exposure of Super-Kamiokande I-V data covering…

Neutron multiplicity measurement in muon capture on oxygen nuclei in the Gd-loaded Super-Kamiokande detector

Kamiokande Collaboration, S. Miki, K. Abe +282

In recent neutrino detectors, neutrons produced in neutrino reactions play an important role. Muon capture on oxygen nuclei is one of the processes that produce neutrons in water C…

First Associated Neutrino Search for a Failed Supernova Candidate with Super-Kamiokande

F. Nakanishi, K. Abe, S. Abe +243

In 2024, a failed supernova candidate, M31-2014-DS1, was reported in the Andromeda galaxy (M31), located at a distance of approximately 770 kpc. In this paper, we search for neutri…
