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…

Statistical sensitivity of neutrinoless double-beta decay exchange mechanism discrimination by tracking experiments

Jason Detwiler, Ke Han, Tao Li

Reconstruction of the individual energies and the opening angle between the electrons emitted in neutrinoless double-beta decay can probe the nature of the beyond-the-Standard-Mode…
