Theia: An advanced optical neutrino detector

The Theia detector design combines next-generation optical detector technology

and advances in water-based liquid scintillator targets to produce a broad

physics program. Advances in photon detectors with fast timing and spectral

sensitivity can be used to distinguish Cherenkov and scintillation signals in

detectors in the 25 to 100 ktonne range, providing sensitivity to low- and

high-energy solar neutrinos, determination of neutrino mass ordering and

measurement of the neutrino CP violating phase, observations of diffuse

supernova neutrinos and neutrinos from supernovae bursts, as well as

neutrinoless double beta decay. This talk will give an overview of the

technological advancements that this experiment will leverage, and the physics

topics thus enabled.
