JUNO's sensitivity to 7Be, pep and CNO solar neutrinos

Abstract

JUNO Experiment is a 20 kt multipurpose liquid scintillator detector located in China, with planned completion of construction in 2023. Its main goal is the Neutrino Mass Ordering determination, exploiting its large target mass and excellent energy resolution of 3% at 1 MeV. Due to its unique properties, JUNO will have a large potential for real-time solar neutrino measurement. A sensitivity study is performed by considering all possible sources of backgrounds including their various concentration levels and a full simulation of the detector response with the usage of reconstructed variables. Results have shown that $^7$Be, pep and CNO solar neutrinos will be measured with an uncertainty highly competitive with respect to the current state-of-the-art in the solar neutrino field obtained by Borexino after a few years of data taking. Furthermore, JUNO has the potential to measure individually for the first time the rate of the two main components of the CNO neutrino flux, $^{13}$N and $^{16}$O solar neutrinos, given that the backgrounds are kept under control. This poster will summarize the strategy used for the estimation of the JUNO sensitivity to $^7$Be, $pep$, and CNO solar neutrinos above the 0.45 MeV threshold and the final results
