Description
DUNE (Deep Underground Neutrino Experiment) is a long-baseline neutrino experiment that will measure the neutrino mass ordering and CP-violation by observing neutrino oscillations. It is planned to be made of four far-site LAr-TPCs (Liquid Argon Time Projection Chamber) of ~17kT each, located at SURF (Sanford Underground Research Facility at 1300 km from the neutrino source, 1.5km below earth’s surface) and a near-site complex hosting different detectors to measure the neutrino flux produced at the LBNF (Long Baseline Neutrino Facility) at Fermilab.
DUNE will also be sensitive to processes beyond the standard model (nucleon decays, HNL, dark matter…) and neutrinos of astrophysical origin, most noticeably supernovas and Solar Neutrinos.
Our star produces a continuous flux of neutrinos as a byproduct of fusion reactions. The products of the two most energetic processes (8B and hep chains) will be accessible to DUNE with neutrino energies centered at 10MeV at an expected interaction rate of ~10⁻³ Hz. DUNE’s solar analysis has the potential of characterizing for the first time the contribution of the hep chain to the solar neutrino spectrum as well as constraining the best-fit measurements of Δm²12 of previous solar and reactor experiments.
In this presentation, DUNE’s analysis of solar neutrinos and its reconstruction capabilities in the low energy range (<20MeV) will be presented.
