Supernova Physics at DUNE

The DUNE/LBNF program aims to address key questions in neutrino physics and astroparticle physics. Realizing DUNE’s potential to reconstruct low-energy particles in the 10–100 MeV energy range will bring significant benefits for all DUNE’s science goals. In neutrino physics, low-energy sensitivity will improve neutrino energy reconstruction in the GeV range relevant for the kinematics of DUNE’s long-baseline oscillation program. In astroparticle physics, low-energy capabilities will make DUNE’s far detectors the world’s best apparatus for studying the electron-neutrino flux from a supernova. This will open a new window to unrivaled studies of the dynamics and neutronization of a star’s central core in real time, the potential discovery of the neutrino mass hierarchy, provide new sensitivity to physics beyond the Standard Model, and evidence of neutrino quantum-coherence effects. The same capabilities will also provide new sensitivity to ‘boosted dark matter’ models that are not observable in traditional direct dark matter detectors.
