Simulation Study of Proton Decay in JUNO

Proton Decay is one of the apparent consequences of Baryon Number Violation, as predicted in many Grand Unified Theories (GUTs). It could give an explanation to the asymmetry of matter and anti-matter in the universe. Among the experiments constructed to search for the clue of proton decays, Super-K has acquired the best results for many decay channels. For the channel p to ν and K+, Super-K has improved the lower limit of proton lifetime to 5.9×10^33 years, which is very close to the prediction of proton lifetime in some GUTs. Jiangmen Underground Neutrino Observatory (JUNO), which is a 20 kton liquid scintillator detector under construction in China, is found to have a better sensitivity based on our recent research. It is expected to reach the order of 1034 years after the running time of ten years. In this poster, the preliminary study including simulation work and algorithm design will be presented.
