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…

Search for neutron decay into an antineutrino and a neutral kaon in 0.401 megaton-years exposure of Super-Kamiokande
Kamiokande Collaboration, K. Yamauchi, K. Abe +261
We searched for bound neutron decay via predicted by the Grand Unified Theories in 0.401 Mtonyears exposure of all pure water phases in the Super-Kamiokande…
