Description
Theia is a proposed large-scale neutrino detector with a novel liquid scintillator target and fast, spectrally-sensitive photon detectors, leveraging both the direction resolution of the Cherenkov signal and the remarkable energy resolution and low detection threshold of a scintillator detector. The Theia physics program spans low-energy neutrino physics, such as solar, geo, supernova burst, diffuse supernova, and a high-sensitivity search for neutrinoless double-beta decay that could reach into the normal hierarchy. Theia has recently received Gateway-0 approval at SNOLAB. Measurements of 𝛿CP and the neutrino mass hierarchy using high-energy neutrinos from the LBNF neutrino beam are also possible if located at SURF. Several technology demonstrators are evaluating the performance of relevant state-of-the-art technologies. This talk will describe the status and plans for Theia.
