The physics potential of detecting 8B solar neutrinos is exploited at the Jiangmen Under-ground Neutrino Observatory (JUNO), in a model independent manner by using three distinctchannels of the charged-current (CC), neutral-current (NC) and elastic scattering (ES) inter-actions. Due to the largest-ever mass of 13C nuclei in the liquid-scintillator detectors and thepotential low background level, 8B solar neutrinos would be observable in the CC and NC interac-tions on 13C for the first time. By virtue of optimized event selections and muon veto strategies,backgrounds from the accidental coincidence, muon-induced isotopes, and external backgroundscan be greatly suppressed. Excellent signal-to-background ratios can be achieved in the CC, NCand ES channels to guarantee the 8B solar neutrino observation. From the sensitivity studiesperformed in this work, we show that one can reach the precision levels of 5%, 8% and 20% forthe 8B neutrino flux, sin2 θ12, and ∆m221, respectively, using ten years of JUNO data. It would beunique and helpful to probe the details of both solar physics and neutrino physics. In addition,when combined with SNO, the world-best precision of 3% is expected for the 8B neutrino fluxmeasurement. |
