Physics prospects of the JUNO experiment

JUNO is a 20 kton multi-purpose liquid scintillator detector currently being built in China in a dedicated underground laboratory and expected to complete the detector construction in 2021. JUNO primary physics goal is the determination of the neutrino mass ordering, with a significance of 3-4 sigma in six years of data taking, by measuring the oscillation pattern of electron antineutrinos coming from two nuclear power plants at a baseline of about 53 km. Besides this fundamental aim, its large target mass, unprecedented energy resolution of 3% at 1 MeV, and vertex reconstruction capability will provide vast opportunities in particle physics and astrophysics. JUNO will have a very rich physics program, which includes the precise measurement at a sub-percent level of the solar neutrino oscillation parameters, the detection of low-energy neutrinos coming from galactic core-collapse supernova, the measurement of the diffiuse supernova neutrino background, the detection of neutrinos coming from the Sun and the Earth (geo-neutrinos). In this paper I will give an overview on the JUNO physics potential and discuss the performance of the JUNO detector for the various proposed measurements.
