Characterization of the scintillation response of water-based liquid scintillator to alpha particles, and implications for particle identification

European Physical Journal C: Particles and Fields, 2023
Next-generation large-scale neutrino detectors, from Eos, at the 1 t scale, to Theia, at the 10 s-of-kt scale, will utilize differences in both the scintillation and Cherenkov light emission for different particle species to perform background rejection.
