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…

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…
