In the era of multimessenger astronomy, neutrinos are essential tools for the study of astrophysical sources. Given the variety of signals expected, advanced detection methods are a key element to improve the sensitivity of an experiment.
The THEIA project aims at combining the advantages of Water Cherenkov and Liquid Scintillator detectors, exploiting recent developments in Water-based Liquid Scintillator and photodetection technology. The innovative detector concept can cover a broad physics program spanning from long baseline to solar neutrinos, with a great potential for Supernova neutrinos detection.
The capability to distinguish neutrino interactions on electrons, protons and oxygen will make it possible to separate Inverse Beta Decay, Elastic Scattering, Charged- and Neutral-Current events. At the same time, the co-detection of scintillation and Cherenkov light offers advanced background discrimination and will permit the observation of the Diffuse Supernova Neutrino Background with high statistical significance.
