Solar neutrino physics with JUNO: analysis strategy and sensitivity studies for Be7, pep, and CNO neutrinos

The JUNO experiment, currently under construction in Jiangmen (China), is a 20 kt multi-purpose liquid scintillator detector. Although it was originally designed for neutrino mass ordering determination, thanks to its large target mass and excellent energy resolution (3% at 1 MeV), JUNO has the potential to provide solar neutrino measurement with an accuracy highly competitive with respect to the current state-of-the-art in the solar neutrino field. The purpose of this poster is to describe the main driving factors for JUNO sensitivity focusing on the so-called intermediate energy solar neutrinos: Be7, pep, and CNO neutrinos. Since the success of the analysis relies on a good understanding of the detector, the complete simulation of the expected signal and background components will be discussed. The analysis was carried out accounting for all the possible sources of backgrounds with different foreseeable level of contaminants, and including thoroughly the electronic response of the detector. The software framework developed to perform the sensitivity studies and the final results will be presented, proving that JUNO will substantially improve the existing measurements on intermediate energy neutrinos.
