THEIA is a potential multi-purpose, large-scale neutrino detector in its very early design stages. It aims to utilize water-based liquid scintillator as a detector medium to study a broad physics program. Its prospects include the capability to detect and measure neutrinos over a vast energy spectrum, with the potential to deduce the hierarchical nature of neutrinos, measure the level of CP violation in the lepton sector and potentially determine whether the neutrino is Majorana in nature. Furthermore, THEIA will be able to study neutrinos from multiple sources including the Earth’s core, the Sun and supernova.
