Description

JUNO is the reactor antineutrino experiment utilizing 20 kilotons liquid scintillator detector. The main goal of the experiment is to provide a determination of the neutrino mass hierarchy at the confidence level of 3-4 standard deviations. The carbon-14 is the natural radioactive isotope that is present in the liquid scintillator. A study of the degradation of the JUNO sensitivity to the neutrino mass hierarchy determination due to carbon-14 contamination was performed using Global Neutrino Analysis framework -- a software tool under development at JINR. This study leads to a requirement of a possible contamination of carbon-14 in the liquid scintillator.
