Search for Diffuse Supernova Neutrino Background in the Full KamLAND Dataset with Neural-Network-Based Event Classification
D. Chernyak, T. Eda, M. Eizuka +63
We report a search for the diffuse supernova neutrino background (DSNB) with the KamLAND detector, targeting electron antineutrinos via inverse beta decay in the neutrino energy ra…
Search for Majorana Neutrinos with the Complete KamLAND-Zen Dataset
S. Abe, T. Araki, K. Chiba +69
We present a search for neutrinoless double-beta () decay of Xe using the full \mbox{KamLAND-Zen 800} dataset with 745\,kg of enriched xenon, corresponding to an e…
Constraints on Fermionic Dark Matter Absorption from Radiochemical Solar-Neutrino Measurements
K. Ishidoshiro, K. Tachibana
We reinterpret classic radiochemical solar-neutrino measurements as ``rate meters'' for additional, non-negative capture-like contributions induced by fermionic dark matter absorpt…
Development of an early warning method incorporating pre-supernova neutrino light curves
Keita Saito, Minori Eizuka, Zhuojun Hu +9
Massive stars () emit neutrinos known as pre-supernova (pre-SN) neutrinos through thermal and nuclear interactions for cooling the stellar core during the fina…
Development of a real-time beam profile monitor for GeV photons and its application in accelerator facilities
Ryoko Kino, Sho Nagao, Takeru Akiyama +15
A real-time beam profile monitoring system is proposed for GeV photon beams at the BM4 beamline of the Mikamine site, Research Center for Accelerator and Radioisotope Science (RARi…
Limits on the Low-Energy Electron Antineutrino Flux from the Brightest GRB of All Time
T. Araki, S. Chauhan, K. Chiba +69
The electron antinuetrino flux limits are presented for the brightest gamma-ray burst (GRB) of all time, GRB221009A, over a range of 1.8-200 MeV using the Kamioka Liquid Scintillat…
