Description
The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed for precision neutrino measurements and is also expected to detect solar neutrinos, including those from the 8B decay chain. A precise understanding of unstable isotopes produced by cosmic-ray muons, such as 8Li and 11Be, is essential, as they constitute one of the dominant backgrounds in the energy region relevant for 8B solar neutrino detection.
This poster presents a study of cosmogenic isotopes at JUNO focusing on event selection, fitting procedures, and production yield determination. The results provide guidance for cosmogenic background rejection and for the estimation of residual background levels in the 8B solar neutrino analysis, contributing to the optimization of solar neutrino analyses at JUNO.
