Neutrino physics with JUNO

The Jiangmen Underground Neutrino Observatory (JUNO), a 20 kton multi-purpose liquid scintillator detector, was proposed with the determination the neutrino mass hierarchy as a primary physics goal. It is also capable of neutrinos from terrestrial and extra-terrestrial sources, including burst neutrinos, diffuse supernova neutrino background, geoneutrinos, neutrinos, solar neutrinos, as well as exotic searches such as decays, dark matter, sterile neutrinos, etc. We present the physics and the anticipated performance of the JUNO detector for various measurements. By detecting reactor antineutrinos from two power plants 53-km distance, JUNO will determine the neutrino mass hierarchy at a 3-4 significance with six years of running. The measurement of antineutrino will also lead to the precise determination of three out of the six parameters to an accuracy of better than 1\\%. Neutrino burst from a core-collapse supernova at 10 kpc would lead to ~5000-beta-decay events and ~2000 all-flavor neutrino-proton elastic events in JUNO. Detection of DSNB would provide valuable information the cosmic star-formation rate and the average core-collapsed neutrino spectrum. Geo-neutrinos can be detected in JUNO with a rate of ~400 per year, significantly improving the statistics of existing geoneutrino. The JUNO detector is sensitive to several exotic searches, e. g. proton via the p\ K^++\\ decay channel. The JUNO detector will provide unique facility to address many outstanding crucial questions in particle and. It holds the great potential for further advancing our quest to the fundamental properties of neutrinos, one of the building of our Universe.
