DUNE as the Next-Generation Solar Neutrino Experiment.

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 100  kton-yr exposure, DUNE could detect ≳10^{5} signal events above 5 MeV electron energy. Separate precision measurements of neutrino-mixing parameters and the ^{8}B flux could be made using two detection channels (ν_{e}+^{40}Ar and ν_{e,μ,τ}+e^{-}) and the day-night effect (>10σ).
