Abstract:
'In this talk we describe in detail the feasibility of detecting $^8$B solar neutrino at JUNO with three reaction channels (neutrino-electron elastic scattering, neutrino-$^{13}$C charged current, and neutral current interactions). A reduced 2 MeV threshold on the recoil electron energy is achievable with optimized background reduction strategies. The advantage of JUNO for charge and neutral current channel detection is a large amount of $^{13}$C (~0.2 kt). With ten years of data taking, about 60,000 ES signals and 600 NC/CC signal are expected. This leads to a simultaneous measurement of sin$^2theta_{12}$ and $Delta m^2_{21}$ using reactor antineutrinos and solar neutrinos in the JUNO detector.'
