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…

Probing Internal Conversion and Dark-Matter-Induced De-excitation of 180mTa with a gamma-ray TES Array
A. Gando, K. Ichimura, K. Ishidoshiro +5
We propose and evaluate a source-as-detector search for the de-excitation of the long-lived isomer in natural tantalum (Ta), using a -ray transiti…
