Many Grand Unified Theories have predicted that the Baryon number is unconservative, which is beyond the Standard Model physics. As a result, proton decay would be an obvious consequence and would become an explanation to the asymmetry of matter and anti-matter in the Universe. Many experiments have been designed and built in order to search for this key sign of a new physics. Among them, the SuperK has obtained the currently best lower limit to the proton life time, in spite of a low detection efficiency. Jiangmen Underground Neutrino Observatory (JUNO), which is a 20 kton liquid scintillator detector under construction in China, has a large sensitivity in these terms. This is, in addition to the detector's large mass, also thanks to a detection efficiency expected to be larger than in SuperK. The results of a preliminary study concerning JUNO potential in the search for proton decay will be presented.
