Theia is a proposed large-scale novel neutrino detector designed with the ability to discriminate between Cherenkov and scintillation signals. The baseline design consists of a cylindrical tank viewed by inward-looking PMTs and filled with water-based liquid scintillator (WbLS), a novel target which would combine reconstruction of particle direction from the Cherenkov signal, with the energy resolution and low threshold of a scintillator detector. Theia would have a broad physics program ranging from low-E solar to high-E accelerator neutrinos.

In this presentation, we focus on the low-E antineutrinos detected via inverse beta decay interactions on protons. Using WbLS as target material for a 25 kT detector located at SURF, we present results for the sensitivity of Theia to both geo- and reactor antineutrinos. Moreover, separation between Cherenkov and scintillation signals offers particle identification capabilities for an additional discrimination between signal and background.
