STATUS AND PHYSICS OF THE JUNO EXPERIMENT

The Jiangmen Underground Neutrino Observatory is a next-generation neutrino experiment under construction in China expected to start data taking in late 2021. As the main goal it aims to address the determination of the neutrino mass hierarchy with 3-4 sigma significance in 6 years. Therefore, it will measure the oscillated energy spectrum of electron anti-neutrinos from two nuclear power plants at 53km baseline with an unprecedented energy resolution of 3% at 1 MeV. A large target size of 20 kt liquid scintillator instrumented by 18000 large 20”-PMTs and 25000 small 3”-PMTs will give the opportunity to contribute to various other current physics topics. These include the measurement of geo-neutrinos, solar-neutrinos, atmospheric neutrinos, and supernova neutrinos. In addition to that JUNO aims to precisely measure the oscillation parameters $θ_{12}$, $Δm^2_{21}$, and$ Δm^2_{ee}$ with sub-percent uncertainties and to search for the proton decay channel into kaons
