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 exposure, DUNE could detect signal events above 5 MeV electron energy. Separate precision measurements of neutrino-mixing parameters and the flux could be made using two detection channels ( and ) and the day-night effect (). New particle physics may be revealed through the comparison of solar neutrinos (with matter effects) and reactor neutrinos (without), which is discrepant by (and could become ). New astrophysics may be revealed through the most precise measurement of the 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.
