DUNE's low energy physics searches

Abstract: The Deep Underground Neutrino Experiment (DUNE) is a long-baseline neutrino experiment that will precisely measure neutrino oscillation parameters, observe astrophysical neutrinos, and search for processes beyond the Standard Model such as nucleon decays, heavy neutral leptons, and dark matter. DUNE will build four liquid argon time projection chambers (LAr-TPC), as far detectors, with a total mass of $\sim70\,\text{kT}$ LAr located at Sanford Underground Research Facility (SURF), $1.5\,\text{km}$ underground. A near-site complex, hosting different detectors, will measure the neutrino flux from an accelerated particle beam ($1.2\,\text{MW}$) produced at the Long Baseline Neutrino Facility (LBNF) at Fermilab, $1300\,\text{km}$ away from SURF. Additionally, this few-MeV low-energy regime is of particular interest for detecting the burst of neutrinos from a galactic core-collapse supernova and solar neutrinos. DUNE will measure oscillation parameters from the solar neutrino flux analysis with much higher precision than previous experiments and discover the yet-unobserved hep flux component.
