Abstract

We show that the Deep Underground Neutrino Experiment (DUNE), with significant but feasible new efforts, has the potential to deliver world-leading results in solar neutrinos. With a 100ktonyr exposure, DUNE could detect 105 signal events above 5 MeV electron energy. Separate precision measurements of neutrino-mixing parameters and the B8 flux could be made using two detection channels (νe+Ar40 and νe,μ,τ+e) and the day-night effect (>10σ). New particle physics may be revealed through the comparison of solar neutrinos (with matter effects) and reactor neutrinos (without), which is discrepant by 2σ (and could become 5.6σ). New astrophysics may be revealed through the most precise measurement of the B8 flux (to 2.5%) and the first detection of the hep flux (to 11%). DUNE is required: No other experiment, even proposed, has been shown capable of fully realizing these discovery opportunities.
